Embodiment 1

[0081] This embodiment provides a firing device, such as figure 1 As shown, the firing device is a stapler, which includes a base frame, a first moving part 13, an operating part 11, a second moving part 21, a support rod 3, a driving part 16, a nail cylinder assembly 17, an anvil assembly 18, a position limiting mechanism and the anti-secondary firing mechanism, wherein the limit mechanism includes the third moving part 14 , the base 223 and the locking member 224 .

[0082] The base frame is a housing 15, preferably composed of a left housing and a right housing. The housing 15 has an inner cavity penetrating along its axial direction; The direction of the distal end of the housing 15 is a first direction, and the direction opposite to the first direction is a second direction.

[0083] The third moving part 14 is preferably a screw rod arranged in the inner cavity of the housing 15, the third moving part 14 can reciprocate along the first direction or the second direction,...

Embodiment 2

[0122] This embodiment provides a firing device. Compared with the structure of the firing device provided in Embodiment 1, the only difference is that the casing 15, the nail barrel 172 and the nail anvil head 181 can be structures of other shapes, specifically The structure is determined by the use environment. For example, the housing 15 and the nail barrel 172 can be a circular tubular structure with a certain curvature, which is more suitable for extending into the interior of the tubular tissue;

[0123] As a further alternative embodiment, the anvil head 181 is a bell structure as a whole, and the opening of the bell structure is located at the distal end and is suitable for being sleeved on the glans. At this time, the firing device is a circumcision stapler.

Embodiment 3

[0125] This embodiment provides a firing device. Compared with the structure of the firing device provided in Embodiment 1 or 2, the only difference is that the toggle 421 is a toggle that is slidably arranged on the wall of the casing 15. One end of the pin is located outside the housing 15 and is suitable for manual control by the operator, and the other end is located in the inner cavity of the housing 15. The force receiving member 422 is driven by the operator manually controlling the toggle pin, and then jointly driven with the fourth reset member 423 The linkage part 41 recovers from the fourth position to the third position;

[0126] As a further alternative embodiment, the fourth reset member 423 may not be provided, and the linkage member 41 can be restored to the third position under the action of the toggle member 421 alone;

[0127] As a further alternative embodiment, the linkage part 41 can be made of non-elastic material. At this time, the linkage part 41 inclu...

Abstract

The invention discloses firing equipment, which comprises a base frame, a first moving part, an operating part and a second moving part, wherein the first moving part is arranged between a starting position and an acting position relative to the base frame in a sliding manner; an abutted point is arranged on the operating part for applying a force tending to an acting position to the first movingpart; the second moving part is arranged between a fixed state and a moving state relative to the base frame in a switchable manner; in the fixed state, the second moving part is abutted against the operating part, and the second moving part forms a pivot point of the operating part; in the moving state, the starting position of the first moving part forms a pivot point of the operating part, andthe firing equipment is in a firing failure state, and thus a safety function of preventing firing is achieved. The second moving part and the operating part of the firing equipment are both in a movable state, compared with the structure which realizes the safety function by locking the position of the operating part, the situation that the structure of the firing equipment is damaged due to theforced movement of the operating part by excessive external force can be completely avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a percussion device. Background technique [0002] Stapler is a device used in medicine to replace traditional manual suturing. At present, the stapler used in clinical practice has the advantages of fast suturing, easy operation, few side effects and surgical complications, and is very popular among clinical surgeons at home and abroad. Admired. [0003] Staplers are divided into circular staplers, linear staplers, and endoscopic staplers according to their functions and structures. Among them, circular staplers are used for the anastomosis of various lumens. The two layers of cavity tissue are sutured together, and the built-in circular knife cuts off excess tissue to form a circular anastomosis to complete the anastomosis of the cavity. At present, it is mainly used in anastomosis of esophagus, stomach, intestine and other digestive tracts, as well as ana...
