Description

Locking gynaecology's tumour operation of moving is with snatching pincers

Technical Field

The utility model belongs to the technical field of medical equipment, and particularly relates to a locking grabbing clamp for gynecological tumor surgery.

Background

When the gynecological tumor is cut or sampled, the gynecological tumor is firstly grasped and positioned, and then the corresponding cutter is adopted for cutting. However, since the tumor is located in the body, it takes a certain time to cut or sample, and during this time, the grasping and positioning of the tumor needs to be maintained, so that the operation of medical staff is facilitated.

Medical staff adopts forceps for operation to grasp when grasping tumors, which is a conventional grasping mode. However, due to the uncertainty of the time required for the excision or sampling of the tumor, the medical staff is required to continuously keep the force to control the forceps to grasp the clamping action of the tumor during the whole excision or sampling process. Once the tumor is resected or sampled for too long, the hands of medical staff are extremely tired and painful, and the forceps are loosened possibly due to the fatigue of the hands, so that the grabbing and positioning of the tumor are lost, and the operation is affected.

Disclosure of Invention

The utility model aims to provide a locking grabbing clamp for gynecological tumor surgery, which is characterized in that two clamp legs of the grabbing clamp are positioned through a positioning pin and a ratchet, and can not be opened in a positioning state, so that medical staff does not need to continuously apply force after clamping a tumor, and the grabbing clamp can keep a grabbing state on the tumor through the structure of the grabbing clamp.

In order to solve the technical problems, the utility model is realized by the following technical scheme:

the utility model provides a locking gynaecology's tumour operation is with snatching pincers, includes first pincers leg and second pincers leg, be provided with the location chi on the first pincers leg, be provided with the locating hole on the second pincers leg, the location chi passes from the locating hole, be provided with the location structure of mutually supporting on second pincers leg and the location chi. And the first clamp leg and the second clamp leg are respectively provided with a finger ring, and the finger rings are used for penetrating into the fingers to operate the first clamp leg and the second clamp leg. The positioning ruler is fixedly connected with the first clamp leg, and penetrates through the positioning hole in the second clamp leg. Therefore, the mutual position between the second clamp leg and the positioning ruler is fixed by adopting a positioning structure, so that the position fixing of the first clamp leg and the second clamp leg is realized. After the positions of the first clamp leg and the second clamp leg are fixed, the first clamp leg and the second clamp leg cannot be opened naturally, the grabbing clamp cannot be released when the grabbing clamp takes the tumor, and at the moment, medical staff is not required to continuously enable force to keep the clamping effect of the grabbing clamp on the tumor.

In order to maintain the clamping effect of the grabbing clamp on the tumor, the grabbing clamp is prevented from releasing the clamped tumor when the grabbing clamp is not subjected to external force or the external force is reduced, and therefore the first clamp leg and the second clamp leg are required to be placed to be opened. Therefore, the ratchet is arranged on the positioning ruler, the spring pin is arranged on the second clamp leg, one end of the spring pin is propped against the ratchet, and the positioning ruler and the second clamp leg are positioned. When the spring pin is abutted against the ratchet teeth, the surface contacted with the spring pin is one tooth surface of the ratchet teeth, so that when the distance between the first clamp leg and the second clamp leg is reduced, the spring pin slides along the tooth surface, the spring pin is compressed, and when the spring pin slides past the highest point of the tooth surface, namely the tooth top, the top end of the spring pin is separated from the tooth surface and is sprung out under the action of the elasticity of the spring pin and then is abutted against the tooth surface of the other tooth. Thus, the ratchet is right triangle or obtuse triangle in shape, and one right angle side or obtuse angle side of the right triangle or obtuse triangle is connected with the body of the positioning ruler. With this construction, the spring pin can slide along the tooth surface in one direction, but when sliding in the other direction, the tooth tips of the ratchet teeth will abut against one side of the spring pin, the ratchet teeth will not exert an axial pressure on the spring pin, and therefore the spring pin will not be compressed, and the spring pin will not slide in that direction. Thus, in the state in which the spring pin abuts against the ratchet, the first jaw leg can be moved in the direction of the second jaw leg, but cannot be moved in the direction away from the second jaw leg, i.e. the first and second jaw legs of the grasping forceps can be closed but cannot be opened.

When the grasping forceps work is completed, the grasping forceps need to be released. Therefore, a structure for controlling the spring pin is needed, so that the spring pin is not abutted against the ratchet any more, and the first clamp leg and the second clamp leg can be opened and closed at will. Therefore be provided with the strip hole on the second pincers leg, be provided with the locating lever on the lateral wall of spring pin, locating lever one end passes strip hole and spring pin fixed connection, the axis of spring pin is parallel with the long lateral wall of strip hole, makes the spring pin is along the axis when back-and-forth movement, the locating lever slides along the long lateral wall of strip hole. When the spring pin is required to be no longer acted on the ratchet, the finger is used for poking the position adjusting rod, so that the position adjusting rod drives the pin shaft of the spring pin to move, and the spring pin can be no longer acted on the ratchet. When shifting the positioning rod and moving, the positioning rod slides along the long side wall of the strip hole, and as the positioning rod is fixedly connected with the side wall of the pin shaft of the spring pin, the pin shaft can move along with the sliding of the positioning rod, and the pin shaft can compress the reset spring, so that when a finger leaves the positioning rod, the pin shaft can return to the initial position under the action of the reset spring and form a positioning effect in cooperation with the positioning ruler.

The utility model has the following beneficial effects:

according to the utility model, the positioning structure between the first clamp leg and the second clamp leg can be used for positioning the position between the first clamp leg and the second clamp leg, so that the positions of the first clamp leg and the second clamp leg are locked, and therefore, when a tumor is clamped in the use process, the positioning structure is used for locking the positions of the first clamp leg and the second clamp leg, so that the first clamp leg and the second clamp leg are prevented from being opened, medical staff can grasp the grabbing clamp without continuous force, the labor intensity of the medical staff is reduced, and the condition that the grabbing clamp is accidentally released in the middle of the operation is avoided.

Detailed Description

The technical scheme of the utility model is clearly and completely described by a specific implementation mode of the embodiment of the utility model with the aid of the attached drawings.

Referring to fig. 1-4, the utility model discloses a locking grabbing clamp for gynecological tumor surgery, which comprises a first clamp leg 1 and a second clamp leg 3, wherein finger rings 2 are arranged on the first clamp leg 1 and the second clamp leg 3, the finger rings 2 are used for finger insertion so as to facilitate the operation of grabbing clamps by medical staff, a positioning ruler 8 is arranged on the first clamp leg 1, a positioning hole 9 is arranged on the second clamp leg 3, the positioning ruler 8 penetrates through the positioning hole 9, and positioning structures matched with each other are arranged on the second clamp leg 3 and the positioning ruler 8.

The positioning rule 8 is provided with a ratchet 16, the second clamp leg 3 is provided with a spring pin, and one end of the spring pin is propped against the ratchet 16 to position the positioning rule 8 and the second clamp leg 3.

From a planar two-dimensional perspective, the sides of the ratchet teeth 16 are triangular in shape and are right or obtuse triangles with the tops of the spring pins resting against the diagonal sides of the triangle. Thus, the spring pin can slide along the hypotenuse of the triangle due to its ability to flex. Since one leg or the obtuse side of the triangle is connected to the body of the positioning rule 8, the spring pin is perpendicular to the body of the positioning rule 8 so that it can contact the hypotenuse. That is, the spring pin can only slide along the hypotenuse of the triangle in a direction towards the first clamp leg 1. When the spring pin slides away from the first clamp leg 1, the vertex of the hypotenuse of the adjacent triangle abuts against the side wall of the spring pin, and the spring pin is not subjected to axial pressure to shorten the spring pin. Therefore, the spring pin cannot move in a direction away from the first clamp leg 1.

It follows that the first and

second legs

1, 3 can be closed but not opened under the cooperation of the spring pin and the ratchet 16. That is, the grasping forceps can only clamp more tightly when the forceps are used for grasping tumors, but cannot be automatically loosened. After the medical staff clamps the tumor, even if the hands are no longer used for force, the first clamp leg 1 and the second clamp leg 3 are not automatically opened, and the clamping effect on the tumor is maintained. In this case, the medical staff only has to hold the grasping forceps to adjust the position of the grasping forceps immediately without maintaining the grip on the tumor by a continuous force. Therefore, even if the operation time is relatively long, the hands of the medical staff should not be fatigued and painful for continuous force.

After the operation is completed, the grasping forceps need to be loosened so as to separate the tumor from the grasping forceps. To open the first and

second legs

1, 3 of the grasping forceps, the spring pin needs to be shortened and no longer acts on the ratchet 16 of the positioning ruler 8. Therefore, the second clamp leg 3 is provided with a bar hole 12, the side wall of the spring pin is provided with a positioning rod 5, one end of the positioning rod 5 passes through the bar hole 12 and is fixedly connected with the spring pin, the axis of the spring pin is parallel to the long side wall of the bar hole 12, and when the spring pin moves back and forth along the axis, the positioning rod 5 slides along the long side wall of the bar hole 12. The position adjusting rod 5 is positioned between the positioning hole 9 and the finger ring 2 on the second clamp leg 3, so that the finger can conveniently operate the position adjusting rod 5. When the grabbing pliers are operated, the thumb penetrates into the ring 2 on the first pliers leg 1, the middle finger is inserted into the ring 2 of the second pliers leg 3, the position adjusting rod 5 is positioned between the index finger and the middle finger, so that the index finger is close to the middle finger, the index finger presses the position adjusting rod 5 to approach the middle finger along the long side wall direction of the strip hole 12, the position adjusting rod 5 drives the spring pin to move, the spring pin is not abutted against the ratchet 16, and then the first pliers leg 1 and the second pliers leg 3 can be optionally opened and closed. The opening direction of the strip hole 12 is along the side surface of the second clamp leg 3, so that the direction of the long side wall of the strip hole 12 is parallel to the direction of the long side of the clamp leg, and the sliding of the positioning rod 5 slides along the long side of the second clamp leg 3.

The spring pin comprises a pin shaft 10 and a reset spring 11, the pin shaft 10 comprises two sections with different diameters, namely a clamping section 14 with a small diameter and a connecting section 13 with a large diameter, the positioning rod 5 is fixedly connected with the connecting section 13 through threads, the clamping section 14 is propped against a ratchet 16, and the connecting section 13 is propped against the reset spring 11. The spring pin is divided into two sections, so that the sizes of the two ends of the spring pin can be flexibly adjusted, the smaller the size of one end contacted with the ratchet 16 is, the smaller the size of the ratchet 16 is, and the finer the positioning between the first clamp leg 1 and the second clamp leg 3 is; the other end needs to be connected with the return spring 11, so that the elastic force of the return spring 11 can continuously act on the pin shaft 10, and therefore, the cross-sectional area of one end of the connecting section 13 needs to be moved, so that the return spring 11 can stably abut against the end face.

The spring pin needs to work through continuous expansion and contraction, then a pin hole 15 for sliding the spring pin is arranged in the second clamp leg 3, the pin hole 15 is a step hole, the clamping section 14 is slidably connected with a section with a small diameter of the pin hole 15, and the connecting section 13 is slidably connected with a side wall with a large diameter of the pin hole 15. The size of the connecting section 13 of the pin shaft 10 is larger than that of the small-diameter section of the step hole, so that the connecting section 13 of the pin shaft 10 cannot enter the small-diameter section of the step hole, and the step hole also plays a limiting role on the spring pin, and the spring pin can be prevented from being ejected from the pin hole 15.

In order to be convenient for install the spring pin still be provided with the compression screw on the second pincers leg 3, be provided with compression screw 4 in the compression screw, the compression screw with the linkage segment 13 of round pin axle 10 is coaxial, reset spring 11's one end is supported and is leaned on compression screw 4. By tightening the compression screw 4, the axial position of the compression screw 4 can be adjusted, thereby adjusting the pressure of the compression screw 4 against the return spring 11. The greater the pressure to which the return spring 11 is subjected, the greater the pressure to the spring pin, so that when the spring pin is worn or the elastic force of the return spring 11 is lowered, the elastic force of the spring pin can be ensured by adjusting the position of the pressing screw 4, thereby enabling the spring pin to operate stably.

The grabbing clamp further comprises a first clamp head 6 and a second clamp head 7, tumors are clamped through the first clamp head 6 and the second clamp head 7, and corrugated teeth 17 are arranged on the opposite surfaces of the first clamp head 6 and the second clamp head 7. The corrugated teeth 17 are shaped as a section of corrugated surface on the clamping surface of the first and second

binding clip

6, 7, which is in the shape of corrugated teeth seen from the side. The corrugated teeth 17 can increase the stability of the first clamp head 6 and the second clamp head 7 in clamping tumors, and avoid the tumors from slipping between the first clamp head 6 and the second clamp head 7 under the action of body fluid, thereby avoiding the occurrence of unstable clamping caused by slipping.

In another preferred embodiment, as shown in fig. 5, the spring pins may complicate and make difficult frequent gripping actions when the above-described grasping forceps are used for ordinary gripping actions. A second spring 18 is thus arranged in the stepped bore-shaped pin bore 15, said second spring 18 bearing at one end against the end face of the connecting section 13 of the pin 10 and at the other end against the stepped end face of the stepped bore. The elastic force of the second spring 18 is smaller than that of the return spring 11, so that when the compression screw 4 is screwed down to withdraw the compression screw 4 from the compression screw hole for a certain distance, the pressure applied to the second spring 18 becomes smaller, and the second spring 18 also expands. The elongation of the second spring 18 displaces the pin 10, so that the pin 10 is moved in the direction of the compression screw 4, so that the pin 10 no longer abuts the ratchet 16. At this time, the first clamp leg 1 and the second clamp leg 3 can be opened and closed freely.

The positioning ruler 8 is an arc-shaped metal strip, and the ratchet 16 is positioned on an arc-shaped surface with a large radius. The positioning ruler 8 can be integrally formed with the first clamp leg 1, and can also be fixedly connected with the first clamp leg 1 through bolts.
