Abstract
The invention discloses a linear stapler for surgical operations. The linear stapler comprises a stapling anvil and a staple chamber, the two of which are arranged oppositely; a stapling anvil housing is fixedly arranged on the outer surface of the stapling anvil, the staple chamber is arranged in a staple chamber frame which is connected with a closing handle by use of a pivot, at least one group of magnetic mechanisms is arranged between the staple chamber frame and the closing handle, and the like poles of the magnetic mechanisms are opposite to each other. The linear stapler has the major beneficial effects that the magnetic mechanisms of which the like poles are opposite to each other are arranged in corresponding positions at the inner sides of the staple chamber frame and the closing handle, and therefore, when the instrument is opened, the like poles of the magnetic mechanisms repel each other so that the instrument can be opened smoothly.
Description
Technical field
The present invention relates to a kind of surgical operating instrument, be in particular a kind of Linear seam cutting device, belong to technical field of medical instruments.
Background technology
Linear seam cutting device is widely used in sewing up and cutting for wound suture, interior tissue in surgical operation, typical Linear seam cutting device discloses as US Patent No. 5129570, have and sew up and two functions of cutting, in carrying out wound suture, by unnecessary cutting tissue.Such Linear seam cutting device generally comprises upper and lower two clamps, and for the closed handle of the upper and lower clamp of closure, be oppositely arranged on nail anvil and the nail bin of upper and lower clamp far-end, be located in nail bin and percussion sheet and the cutting knife that can move relative to described nail bin simultaneously, and push button for driving described percussion sheet and cutting knife to move.In described nail bin, be disposed with suturing nail, described percussion sheet promotes in order successively pushing slice of nail and pushes suturing nail to nail anvil, and described cutting knife cuts off the tissue between nail bin and nail anvil.
The closed handle of existing Linear seam cutting device and nail bin frame are to rely on bearing pin to pivot together, and wherein, bearing pin is through closed handle and pin shaft hole corresponding on nail bin frame.Shell fragment is set in closed handle, drives closed handle to rotate with respect to nail bin frame, due to such structure setting, shell fragment free end is closer apart from bearing pin, higher for the elastic force requirement of shell fragment, causes apparatus to be not easy to be flicked, and has the risk of inefficacy.
Summary of the invention
The object of the invention is to propose a kind of surgical operation Linear seam cutting device simple in structure, by the improvement to structure, apparatus can be opened easily.
Object of the present invention, will be achieved by the following technical programs:
A kind of surgical operation Linear seam cutting device, comprise the nail anvil and the nail bin that are oppositely arranged, described nail anvil outer surface is installed with nail anvil shell, described nail bin is located in a nail bin frame, described nail bin frame and closed handle are pivotally connected, between described nail bin frame and described closed handle, be provided with at least one group of magnetic force mechanism, described magnetic force mechanism homopolarity is relative.
Preferably, described magnetic force mechanism comprises two magnetic sheets that arrange on correspondence position inside described nail bin frame and described closed handle respectively, and described two magnetic sheet homopolarities are relative.
Preferably, comprise symmetrically arranged two groups of magnetic force mechanisms, described in every group, magnetic force mechanism comprises two magnetic sheets that arrange on correspondence position inside described nail bin frame and described closed handle respectively, and described magnetic sheet homopolarity is relative.
Preferably, described magnetic force mechanism is electromagnetic assembly, and described electromagnetic assembly comprises two magnetic sheets and the Electromagnetic Control portion that inside described nail bin frame and described closed handle, on correspondence position, arrange respectively.
Preferably, in described closed handle, be also provided with the shell fragment resetting for ordering about described closed handle.
Beneficial effect of the present invention is mainly reflected in: by the magnetic sheet that homopolarity is relative being set at nail bin frame with on corresponding position, closed handle inner side respectively, when apparatus is in the time opening, two magnetic sheet two like magnetic poles repel each others, contribute to apparatus to open.

Wherein: 1, nail anvil; 2, nail bin; 3, nail anvil shell; 4, nail bin frame; 5, closed handle; 6, magnetic sheet.
Detailed description of the invention
As shown in Figure 1, a kind of surgical operation Linear seam cutting device, consistent with prior art, comprise the nail anvil 1 and the nail bin 2 that are oppositely arranged, described nail anvil 1 outer surface is provided with nail anvil shell 3, and described nail bin 2 is arranged in a nail bin frame 4, and described nail bin frame 4 is pivotally connected with closed handle 5.
Feature of the present invention is: between described nail bin frame 4 and described closed handle 5, be provided with one group of magnetic force mechanism, described magnetic force mechanism comprises two magnetic sheets 6 that arrange on described nail bin frame 4 and described closed handle 5 inner side correspondence positions respectively, described magnetic sheet homopolarity is relative, when Linear seam cutting device is opened, described magnetic sheet two like magnetic poles repel each other is beneficial to be opened.
In the time that Linear seam cutting device is in closure state, specifically shown in Figure 2, the mutual expelling force maximum between two magnetic sheets, but due to closed handle 5 be provided with for the fixing lock dog of nail bin frame 4, so Linear seam cutting device can stably be in closure state; When Linear seam cutting device is during in open mode, specifically shown in Figure 3, press the release-push of apparatus, due to two magnetic sheet two like magnetic poles repel each others, thereby make the closed handle 5 can self-resetting, the pivot on nail bin frame 4 rotates, thereby can open easily apparatus.
Certainly,, because closed handle 5 is bending parts, so be provided with symmetrically 2 magnetic sheets 6 in order to balance on its bending edges, this is best scheme.Similarly, two magnetic sheets 6 that homopolarity is relative need be also set in the relevant position of nail bin frame 4.Described magnetic force mechanism can also be electromagnetic assembly, described electromagnetic assembly comprises two magnetic sheets 6 and the Electromagnetic Control portion that on described nail bin frame 4 and described closed handle 5 inner side correspondence positions, arrange respectively, carry out the break-make of controlling magnet by Electromagnetic Control portion, only in the work of needs magnetic force mechanism, make its logical magnetic, idle time, magnetic force mechanism does not have magnetic, improves the serviceability of apparatus.
Magnetic sheet 6 operated by rotary motion of this preferred embodiment are on the position of the pivot hole away from nail bin frame 4, and like this, the arm of force of magnetic force is long, and magnetic sheet is large to the corresponding meeting of the moment of closed handle.
In the present invention, can be opened better in order to ensure Linear seam cutting device, shell fragment like the prior art can be set in described closed handle.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming, within all dropping on protection scope of the present invention.
