Abstract
The utility model provides a nail-resisting seat component of an endoscope internal cutting anastomat, which comprises a lower clamp and a nail-resisting seat, wherein the tail ends of the lower clamp and the nail-resisting seat are connected through a rotating shaft; a buckle is arranged at one end of the nail abutting seat, which is far away from the rotating shaft, and the buckle is movably connected with the nail abutting seat through the rotating shaft and is in a closed state; one side of the lower clamp, which is far away from the nail abutting seat, is provided with a notch which penetrates in the radial direction; the utility model discloses can effectively solve the chamber mirror anastomat and support the phenomenon of the dislocation of skidding between nail seat and the lower clamp after pressing from both sides tightly.
Description
Technical Field
The utility model belongs to the technical field of the endoscope internal cutting anastomat, concretely relates to endoscope internal cutting anastomat support nail seat subassembly.
Background
The endoscope cutting anastomat is one of important instruments for the endoscope operation, replaces the traditional manual suture, utilizes titanium nails to separate or inosculate tissues, is simple and rapid to operate, greatly shortens the operation time, facilitates the anastomosis of narrow operation fields and deeper parts which are difficult to manually operate, is accurate, firm and reliable, and obviously reduces the incidence rate of anastomotic fistula. However, when the titanium nail stapler is used, the tissue fluid can increase the probability of slipping of the nail abutting seat during clamping, once the clamping is displaced, the titanium nail can damage a part to be anastomosed during anastomosis, or the titanium nail cannot be bent in place during percussion, and the success rate of the operation can be reduced.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model provides a following technical scheme: the nail abutting seat assembly of the endoscopic incision anastomat comprises a lower clamp and a nail abutting seat, wherein the lower clamp is connected with the tail end of the nail abutting seat through a rotating shaft; a buckle is arranged at one end of the nail abutting seat far away from the rotating shaft, the buckle is movably connected with the nail abutting seat through a fixed shaft, and the buckle is in a closed state; one side of the lower clamp, which is far away from the nail abutting seat, is provided with a notch which penetrates in the radial direction.
Preferably, the cross section of the notch is arc-shaped, and a limiting block is arranged at the opening of the notch.
Preferably, the part of the buckle embedded in the notch is wrapped by a rubber sleeve.
Preferably, the width of the inner side of the buckle is the same as the width of the lower clamp.
Preferably, two rows of positioning columns are arranged on the contact surface of the nail abutting seat and the lower clamp.
Compared with the prior art, the beneficial effects of the utility model are that: this application improves through the structure to supporting nail seat and lower clamp to guarantee to carry out the centre gripping to the position of variation in size and can both guarantee not the slippage when identical, increased the frictional force between holder and the tissue, can adopt the mode of direct locking to the less tissue of area, easy operation, and can improve the success rate of performing the operation greatly.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 3, the nail abutting seat assembly of the endoscopic incision anastomat comprises a lower clamp 1 and a nail abutting seat 2, wherein the tail ends of the lower clamp 1 and the nail abutting seat 2 are connected through a rotating shaft 3; a buckle 4 is arranged at one end of the nail abutting seat 2 far away from the rotating shaft 3, the buckle 4 is movably connected with the nail abutting seat 2 through a fixed shaft 5, and the buckle 4 is in a closed state and can rotate around the fixed shaft 5 as a center; one side of the lower clamp 1, which is far away from the nail abutting seat 2, is provided with a notch 6 which penetrates through in the radial direction.
The cross-section of the notch 6 is arc-shaped, and a limiting block 7 is arranged at the opening of the notch 6. The part of the buckle 4 embedded in the notch 6 is wrapped by a rubber sleeve 8. The width of the inner side of the buckle 4 is the same as that of the lower clamp 1. When the volume of the clamped tissue with anastomosis is small, the head ends of the lower clamp 1 and the nail abutting seat 2 can be contacted with each other, the buckle 4 can be directly buckled into the notch 6 at the moment, the rubber sleeve 8 enables the buckle 4 to be easily pressed into the notch 6 under the extrusion of the limiting block 7 without falling out due to self gravity, and the width of the inner side of the buckle 4 is the same as that of the lower clamp 1 so as to ensure the fixation between the lower clamp 1 and the nail abutting seat 2 and ensure that the lower clamp 1 and the nail abutting seat 2 cannot deviate when being vibrated; the arc structure in the notch 6 is convenient for taking the buckle 4 out of the notch 6 after anastomosis is finished, and the resistance of the special-shaped inner wall can not be applied.
In order to increase the friction force between the nail supporting seat and the tissue to be anastomosed in the clamping state, two rows of positioning columns 9 are arranged on the contact surface of the nail supporting seat 2 and the lower clamp 1, and when the clamped tissue area is larger, the positioning columns 9 can still ensure that the friction force of the contact surface of the nail supporting seat 2 is increased, so that the anti-skidding is realized.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the description, and must be determined according to the scope of the claims.
