Detailed Description

The technical scheme of the patent is further described in detail below with reference to the specific embodiments.

Embodiment one:

as shown in fig. 1 and 2, the present embodiment provides a laparoscopic needle holder including a forceps body 1; one end of the clamp body 1 is provided with a clamp head 3, and the other end of the clamp body 1 is provided with a first clamp handle 4 and a second clamp handle 5; the clamp head 3 is divided into a first clamp head and a second clamp head, the first clamp head is connected with the first clamp handle 4, the second clamp head is connected with the second clamp handle 5, and the intersection of the first clamp handle 4 and the second clamp handle 5 is connected with the clamp body 1 in a shaft way, so that the effect of driving the clamp head 3 to open and close when the first clamp handle 4 and the second clamp handle 5 move relatively is achieved.

The outside of the forceps head 3 is sleeved with a tube sleeve 2 made of medical silica gel, so that the forceps head 3 is prevented from malfunctioning because blood or human tissues in operation enter the small part of the forceps head 3 crack.

The first pincers handle 4 is connected with arc 6 down, has seted up arc slot 8 in the arc 6, is provided with arc piece 11 down the second pincers handle 5, and arc piece 11 embedding is in arc slot 8 and arc piece 11 can slide in arc slot 8.

The scheme of the embodiment has no great difference with the existing product when in use; the advantage of this embodiment lies in that having formed the direction through arc wall and arc piece between first pincers handle and the second pincers handle, the operator is in the use, and the condition that first pincers handle and second pincers handle formed the dislocation is difficult to take place, makes the operator can concentrate more on with the operation itself, does not need worry pincers handle because the dislocation influences the operation progress.

Example two

Referring to fig. 1 and 2, this embodiment is a modification of the first embodiment, specifically, a clamp handle spring 9 is disposed in an arc-shaped slot 8, one end of the clamp handle spring 9 is connected to the inner side of the arc-shaped slot 8 near the first clamp handle 4, and the other end of the clamp handle spring 9 is connected to an arc-shaped block 11.

When the clamping is needed, the second clamp handle is required to move towards the first clamp handle, the second clamp handle moves towards the first clamp handle in the chute 8 with the arc-shaped block 11, and the spring 9 is compressed at the moment, so that a user can clearly feel what force is needed to operate;

when the clamping object is required to be loosened, the compression force of the clamp handle spring disappears, the first clamp handle is far away from the second clamp handle under the action of the clamp handle spring, and the first clamp head and the second clamp head correspondingly loosen the clamping object.

The clamp handle spring can make an operator exert force on one action, so that the strength of the operator is reduced.

Example III

Referring to fig. 1 and 2, this embodiment is a modification of the first embodiment, specifically, a side of the arc plate 6 away from the first clamp handle 4 is in threaded connection with a limit adjusting nut 12, one end of the limit adjusting nut 12 extends into the arc slot 8, and an effect of limiting the movement position of the arc block 11 can be achieved by rotating the limit adjusting nut 12.

The angle that the binding clip among the prior art was opened is fixed, if need adjust the angle of opening then need change corresponding equipment, and very inconvenient, under certain circumstances, binding clip 3 generally need go deep into the internal narrow and small position of patient, and operable space is little, and the too big angle that opens of impermissible binding clip is too much, and the too big angle that opens and shuts extremely easily leads to the damage of tissue, only relies on operating personnel to think that there is the uncontrollable condition of operation in the opening and shutting of control angle, and change corresponding equipment also has the unchangeable condition of operation.

In the embodiment, when the arc-shaped groove 8 and the arc-shaped block 11 are used for guiding the opening and closing, the opening and closing angle of the clamp head 3 is limited according to the operation requirement by using the limiting adjusting nut 12, so that misoperation of a doctor is avoided, and the success rate of the operation is improved.

Before use, the depth of the limit adjusting nut 12 is adjusted according to the operation requirement, so that the moving distance of the arc-shaped block 11 in the arc-shaped groove 8 is changed, and the opening and closing size of the clamp head 3 is further changed.

Example IV

Referring to fig. 1 to 4, this embodiment is a modification of the first embodiment, specifically, a latch device 7 is provided on the second grip 5, and the latch device 7 includes a shift head 701, a pin 702, a pin 703, a pin bush 704, and a latch spring 707; the pin 702 is sleeved with the pin sleeve 704, the upper end of the pin 702 is connected with the shifting head 701, the lower end of the pin 702 is connected with the pin 703, and the latch spring 707 is arranged at the bottom of the inner side of the pin sleeve 704 and connected with the bottom of the pin 702; an L-shaped groove 705 is formed in the inner side of the pin sleeve 704, a protruding point 706 is arranged on the pin rod 702, the protruding point 706 is connected with the L-shaped groove 705 in a sliding way, and when the protruding point 706 moves from a longitudinal groove to a transverse groove of the L-shaped groove 705, rebound of the pin rod 702 is prevented, so that a limiting effect is achieved. The arc plate 6 is also provided with a plurality of bolt holes 10, and the pins 703 are inserted into the bolt holes 10. The bolt device 7 is matched with the bolt hole 10 to realize the effect of fixing the opening and closing angle of the clamp head 3; the pin 703 of the present embodiment may be matched with a plurality of pin holes 10, so that an operator may choose according to actual situations.

When in use, fingers of a user are respectively sleeved into the rings of the second clamp handles 5 of the first clamp handle 4 to operate, the user can press the shifting head 701 and then rotate the shifting head 701 at a required clamping fastening time, the convex points 706 are driven by the shifting head 701 to move along the longitudinal grooves of the L-shaped sliding grooves and enter the transverse grooves under the rotation, the locking effect is realized, and at the moment, the pins 703 are inserted into the bolt holes 10, so that the clamp head 3 realizes the clamping effect. When the locking and unlocking is performed, the shifting head 701 is reversely rotated, the pin 703 is driven to move from the transverse groove to the longitudinal groove of the L-shaped groove, and the pin 703 is ejected from the bolt hole 10 under the elastic force of the bolt spring 707, so that the unlocking is completed.

Fifth embodiment:

in the first embodiment, the pulling head 701 of the latch device 7 is in a vertical pulling piece shape, and the surface of the pulling head 701 is provided with anti-slip lines, which can facilitate one-hand operation by friction force, so that the user's finger can move and rotate the pulling head 701 more easily.
