detailed description

Referring to Fig. 1, and referring to Fig. 2 to Fig. 7, the laparoscopic detachable vascular blocking clamp of the present invention includes a cannula, a manipulation mechanism and a blocking clamp 1, and the blocking clamp 1 is arranged in the sleeve and passed through The operating mechanism controls its action. The sleeve includes a front sleeve 2 and a rear sleeve 3. The front sleeve and the rear sleeve are detachably embedded and connected; the operating mechanism includes a front operating mechanism and a rear operating mechanism. The front operating mechanism It is movably connected with the blocking clamp, and the rear manipulating mechanism is detachably movably connected with the front manipulating mechanism.

Referring to Fig. 2, Fig. 3, Fig. 4, the front operating mechanism among the present invention comprises detachable connecting body 4, pull rod 5 and two connecting rods 6, and detachable connecting body 4 is provided with for connecting with rear operating mechanism A T-shaped slot 41 for detachable connection, and four elastic buckles 42 for connecting with the buckle of the front casing, one end of the pull rod 5 is fixedly connected with the detachable connecting body, and the other end is movable with the two connecting rods 6 The other ends of the two connecting rods 6 are respectively movably connected with the two pliers handles of the blocking pliers 1, and a parallelogram telescopic structure is formed between the two connecting rods and the two pliers handles.

Referring to Fig. 1 and Fig. 5, the rear operating mechanism in the present invention includes a handle 7, a push button 8, a push rod 9, a handle 10 and a connecting rod splitting mechanism, the handle 7 is provided with a push button hole and a handle hole, and the push button 8 is set in the push button hole and connected with the push rod 9; the handle 10 is set in the handle hole and connected with the connecting rod opening and closing mechanism, and the connecting rod opening and closing mechanism is detachably connected with the front operating mechanism; push the push button The opening and clamping of the blocking jaw can be realized, and the separation and closing of the front operating mechanism and the rear operating mechanism can be realized by pulling the handle.

The above-mentioned connecting rod splitting mechanism includes a first connecting rod 11, a second connecting rod 12, a third connecting rod 13 and a fourth connecting rod 14. One end of the first connecting rod and the second connecting rod is connected with the handle 10, and the other ends are respectively It is movably connected with the third connecting rod and the fourth connecting rod, and the third connecting rod and the fourth connecting rod are connected in a cross-movable manner, and form a V-shaped fork at the other end, and the inside of the V-shaped fork is connected with a return spring 15, V-shaped The outer sides of the fork are respectively connected with a short shaft 16, which can be embedded in the T-shaped slot 41 on the detachable connecting body to realize the detachable connection with the T-shaped slot; the handle 10 is connected with the third connecting rod and the second The cross-joints of the four links are movably connected.

Referring to Fig. 1 and Fig. 7, the front sleeve 2 in the present invention is provided with four slots 21 adapted to the four elastic buckles of the front operating mechanism.

Working process principle of the present invention can be described as follows in conjunction with accompanying drawing:

The first step is to block the clamp to clamp the target blood vessel: the clamp is in the open state at the beginning. During the operation, the blood vessel blocking forceps is inserted into the micro-hole of the abdominal cavity opening, reaches the designated target blood vessel, and the push button is turned in 8 directions. After pushing for a certain distance, at this time, the four elastic buckles 42 of the front operating mechanism buckle the corresponding four slots 21 on the front cannula 2, and block the clamp to close and clamp the target blood vessel at the same time.

The second step is to block the separation of the clamp from the operating mechanism: first separate the front casing 2 and the rear casing 3, then separate the front operating mechanism and the rear operating mechanism, and turn the knob 31 to obtain the originally twisted front casing 2 and rear casing 3 loosen. The doctor holds the handle 7, holds the handle 10 tightly, puts the return spring 15 in a compressed state, moves the entire rear operating mechanism backward, and breaks away from the T-shaped slot 41 in the front operating mechanism, that is, separates it from the blocking jaw .

The third step is to find the blocking clamp, and the operating mechanism is integrated with the blocking clamp: first close the operating mechanism and then close the casing. After the treatment of the lesion in the body is completed, the operating mechanism enters the body. After finding the clamp, hold the handle 10 tightly so that the return spring 15 is in a compressed state. At the same time, the two short shafts 16 enter the T-shaped groove 41 and can be released. The handle 10 and the return spring 15 reset and are stuck in the T-shaped slot. Then turn the knob 31 so that the separate front and rear sleeve pipe turnbuckles are closed, and now the operating mechanism is integrated with the clamp.

The fourth step is to loosen the blocking clamp: push the push button 8 forward for a certain distance, at this time, the four elastic buckles 42 are separated from the four locking grooves 21, the blocking clamp is opened, and the target blood vessel is released.
