Problems solved by technology

[0006] However, in the safety device of the above-mentioned stapler, the operator judges whether the stapler is within the range of the triggerable position by observing the pointing position of the pointer in the indicating window during the operation, but due to many interference factors during the operation, plus The deviation of the operator's line of sight angle will cause the doctor to misjudge and press the handle by mistakenly thinking that the firing position has been reached, but at this time the pointer is not actually pointing to the firing position range, and the end of the safety lever is still against the handle The bump on the handle acts as a limiter. If the operator uses a large force to press the handle at this time, it will cause damage to the shell of the stapler and its internal structure.

Embodiment 1

[0089] This embodiment provides a stapler, such as figure 1 As shown, it includes a base frame 1, an anvil assembly 7, a nail cylinder assembly 6, a second driving member 42, a first moving part 2, a second moving part 3, a third moving part 4, an operating part 5, and a pole 52 , the first driving member 41, the limit mechanism and the anti-secondary firing device; wherein the stapler is a stapler; the limit mechanism includes a first reset member 83, a second reset member 84, a third reset member 85, and a fourth reset member 86 , transition piece 81 , locking piece 82 .

[0090] Such as Figure 14 As shown, the base frame 1 is the shell of the stapler, and the shell is preferably composed of a left shell and a right shell; The proximal end is provided with a fourth limiting portion 14 , a fifth limiting portion 15 , a first limiting portion 11 , a second limiting portion 12 and a third limiting portion 13 .

[0091] Such as figure 1 and Figure 9 As shown, the third mo...

Embodiment 2

[0128] 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, the nail barrel 61 and the anvil head 71 can be of other shapes. The specific structure Determined by the use of the ring shape, for example, the housing and the nail barrel 61 can be a circular tubular structure with a certain curvature, which is more suitable for extending into the interior of tubular tissues;

[0129] As a further alternative embodiment, the anvil head 71 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

[0131] This embodiment provides a firing device. Compared with the structure of the firing device provided in any one of Embodiments 1-2, the only difference is that the first driving member 41 is slidably arranged on the wall surface of the casing. One end of the toggle pin is located outside the casing and is suitable for manual control by the operator, and the other end is located in the inner cavity of the casing. The force receiving member 92 is driven by the operator manually controlling the toggle pin, and then the linkage part 91 is moved from the first The four position is reset to the third position.

Abstract

The invention discloses firing equipment, which comprises a base frame; a first moving part, a second moving part, an operating part, a support rod, a limiting mechanism and a driving piece, wherein the first moving part is arranged in a sliding manner; the second moving part is arranged to switch between a moving state and a fixed state; one end of the operating part is hinged on the first movingpart; both ends of the support rod are respectively hinged on the operating part and the second moving part; the limiting mechanism is arranged between a first position and a second position in a movable manner, the first position corresponds to the moving state, and the firing equipment is in a firing failure state; the first driving piece is used for driving the limiting mechanism to move to the second position, the second position corresponds to the fixed state, the firing equipment is in a firing state, and a safety function of the limiting mechanism is started; and when the firing equipment is in a failure state, the second moving part and the operating part are both in a movable state. Compared with the traditional structure which realizes the safety function by locking the positionof the operating part, the situation that the operating part is forced to move by excessive external force when the safety function is started and damages the firing equipment can be 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 is favored by clinical surgeons at home and abroad because of its advantages of fast suturing, easy operation, and few side effects and surgical complications. and respected. [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 the anastomosis of esophagus, stomach, intestine and other digestive tracts, as wel...
