Description

Technical Field

[0001] This invention belongs to the technical field of sampling forceps, specifically relating to disposable cervical biopsy forceps and their usage method. Background Technology

[0002] Cervical cancer is one of the most common malignant tumors in women, and early diagnosis and treatment are crucial. A cervical biopsy is the gold standard for diagnosing precancerous lesions and cervical cancer. It involves obtaining a small tissue sample from a suspicious area of ​​the cervix for pathological analysis, providing a decisive basis for clinical diagnosis. Currently, most cervical biopsy forceps used in clinical practice are reusable instruments that can be sterilized, but they have the following inherent defects during use: 1. Risk of cross-infection: Although sterilized by high temperature and high pressure, the complex structure of the forceps (such as joints and gaps) may have blind spots in sterilization, which may lead to the potential risk of cross-infection between patients; 2. Performance degradation: Repeated sterilization and use can cause the forceps blades to become dull, the joints to loosen, and the springs to become weak, thereby affecting the efficiency and effectiveness of tissue retrieval and potentially leading to tissue crush injuries or sampling failure. 3. Cost and management costs: Reusable medical devices require professional cleaning, disinfection, sterilization, storage and management processes, which increases the hospital's human and material costs; 4. Limited functionality: Traditional biopsy forceps can only perform the grasping operation, but cannot control the force during sampling, which may result in excessive force when grasping tissue, causing injury or discomfort to the patient. The aforementioned phenomenon has become a problem that urgently needs to be solved by those in this field. Summary of the Invention

[0003] The purpose of this invention is to provide a disposable cervical biopsy forceps and its method of use, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a disposable cervical biopsy forceps and its method of use, comprising a handle, a head, and a rod. The handle includes a movable handle and a fixed handle, and the head includes a lower clamp and an upper clamp. A shaft is connected to the middle of the fixed handle, the movable handle is fixed to the shaft, and a torsion spring is sleeved on the outer side of the shaft. The rod is fixedly installed on the left end of the fixed handle, and the lower clamp is welded and fixed to the left end of the rod. A through hole is provided in the middle of the fixed handle, the rod, and the lower clamp, and a sliding rod is slidably connected in the through hole. The upper clamp is axially connected to the left end of the sliding rod, and the bottom of the upper clamp is embedded in the lower clamp, and the two are axially connected. Arc-shaped blocks are fixed to the outer sides of both the front and rear ends of the shaft, and the arc-shaped blocks are arranged opposite each other. Pressure grooves are provided on the front and rear sides of the inner wall of the fixed handle, the arc-shaped blocks are located in the pressure grooves, and the shaft is rotatably connected to the pressure grooves.

[0005] The present invention further illustrates that the inner wall of the pressure groove is provided with an embedding groove, and a silicone block is embedded inside the embedding groove, the silicone block being in contact with the outer side of the arc-shaped block.

[0006] The present invention further illustrates that the inner wall of the pressure groove is provided with a plurality of grooves, and the plurality of grooves are evenly arranged in sequence, and a sphere is embedded in one of the grooves; the sphere is in contact with one end of the arc-shaped block.

[0007] The present invention further illustrates that the inner wall of the pressure groove and the sphere are both magnetic, and the magnetic poles are the same.

[0008] The present invention further illustrates that the arc-shaped block also has magnetism, and the magnetic poles are opposite to those of the sphere.

[0009] The present invention further illustrates that the magnetic poles between the arc-shaped block and the inner wall of the pressure groove are opposite.

[0010] The present invention further illustrates that the inner wall of the pressure groove is provided with a sliding groove, and the two ends of the sliding groove are respectively connected to the outermost and innermost grooves.

[0011] The present invention further illustrates that the groove and the sphere fit together, and the connection between the groove and the recess is trapezoidal, with the two trapezoidal portions arranged opposite to each other.

[0012] The present invention further describes the method of use as follows: Step S1, preoperative preparation and examination: verify that the product packaging is intact and within the expiration date, routinely disinfect the vulva and vagina, fully expose the cervix with a speculum, wipe away secretions on the surface of the cervix, aseptically open the packaging, take out the sampling forceps, and confirm that the upper clamp is in the open state; Step S2, precise positioning: the operator holds the forceps handle and gently inserts the sampling forceps through the speculum, so that the forceps head is close to the target lesion area on the surface of the cervix, and accurately covers the target area by utilizing the pre-opening characteristic of the forceps head; Step S3, press the forceps handle, and under the action of the torsion spring, the upper clamp is closed by pulling the sliding rod, cutting off the target tissue block and accommodating it in the lower clamp; Step S4, sample removal and processing; Step S5, the used disposable sampling forceps are disposed of as medical waste and placed in the designated sharps box or medical waste collection container; Step S6, postoperative management: apply pressure to the cervical biopsy wound to stop bleeding, and after observing that there is no active bleeding, remove the speculum.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention completes the sampling surgery with sampling forceps, which is simple to operate and highly safe. At the same time, when the shaft rotates, it drives the arc-shaped block to rotate around its center. The arc-shaped block and the silicone block squeeze and rub against each other, which slows down the rotation of the shaft, so as to accurately control the force of grasping the tissue, greatly improving the safety of the surgery. Moreover, after the silicone block is subjected to force, it applies resistance to the arc-shaped block, thereby further reducing the strength and force when grasping the tissue. During the repositioning process, the magnetic force between the inner wall of the pressure groove, the ball, and the arc-shaped block slows down the repositioning speed of the arc-shaped block, thus preventing excessive force when loosening the tissue from causing it to detach from the forceps and providing protection.

[0015] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-6 The present invention provides a technical solution: a disposable cervical live sampling forceps and its method of use, including a forceps handle, a forceps head and a forceps bar 1, the forceps handle including a movable handle 2 and a fixed handle 3, and the forceps head including a lower clamp 4 and an upper clamp 5; A shaft 31 is connected in the middle of the fixed handle 3. The movable handle 2 is fixed on the shaft 31, and a torsion spring 6 is sleeved on the outside of the shaft 31. The clamp 1 is fixedly installed on the left end of the fixed handle 3. The lower clamp 4 is welded and fixed to the left end of the clamp 1. A through hole is provided in the middle of the fixed handle 3, the clamp 1 and the lower clamp 4, and a slide rod 7 is slidably connected in the through hole. The upper clamp 5 is axially connected to the left end of the slide rod 7, and the bottom of the upper clamp 5 is embedded in the lower clamp 4, and the two are axially connected. Arc-shaped blocks 311 are fixed on the outer sides of both the front and rear ends of the shaft 31, and the arc-shaped blocks 311 are arranged opposite to each other. Pressure grooves 32 are provided on both the front and rear sides of the inner wall of the fixed handle 3. The arc-shaped blocks 311 are located in the pressure grooves 32, and the shaft 31 is rotatably connected to the pressure grooves 32. During the live sampling process, the forceps are held and the forceps head is inserted into the uterus, aligned with the tissue to be sampled, and the movable handle 2 is pressed. The groove of the second locking block 21 contacts one end of the torsion spring 6, squeezing one end of the torsion spring 6. The torsion spring 6 is squeezed and deformed. At the same time, the movable handle 2 rotates around the shaft 31, and its left side drives the slide rod 7 to move to the left. The left end of the slide rod 7 presses against the upper clamp 5, causing it to rotate through the shaft of the lower clamp 4. The upper clamp 5 is pressed down into the lower clamp 4 to clamp the tissue. After that, it is removed, and the movable handle 2 is released. The torsion spring 6 loses its squeezing force and thus resets, allowing the movable handle 2 and the upper clamp 5 to reset. The tissue is then released and placed into a sampling dish to complete the sampling procedure. The operation is simple and highly safe. At the same time, when the shaft 31 rotates, it drives the arc-shaped block 311 to rotate around its center. By squeezing against the inner wall of the pressure groove 32, it is easier for the operator to accurately control the force of the pressing handle 2, thereby controlling the force when the clamp head clamps the tissue, preventing unstable control of the pressing force of the pressing handle 2, and playing a deceleration role, resulting in higher precision in force control.

[0017] The inner wall of the pressure groove 32 is provided with an embedding groove 323, and a silicone block 324 is embedded inside the embedding groove 323. The silicone block 324 is in contact with the outer side of the arc-shaped block 311. When the shaft 31 rotates, it drives the arc-shaped block 311 to rotate around its center. The arc-shaped block 311 and the silicone block 324 squeeze and rub against each other, which slows down the rotation of the shaft 31, so as to accurately control the force of grasping the tissue and greatly improve the safety of the surgery. Furthermore, the silicone block 324 applies resistance to the arc-shaped block 311 after being subjected to force, thereby further reducing the strength and force when grasping the tissue.

[0018] The inner wall of the pressure groove 32 is provided with a number of grooves 321, and the grooves 321 are evenly arranged in sequence, with a ball 322 embedded in one of the grooves 321. One end of the sphere 322 is in contact with the arc-shaped block 311; When the arc-shaped block 311 rotates around the center of the shaft 31, the arc-shaped block 311 contacts the ball 322 and squeezes the ball 322. The ball 322 is pushed and enters the next groove 321 through one groove 321. The ball 322 applies resistance to the arc-shaped block 311, further slowing down the rotation speed of the shaft 31. This avoids the force being out of control during the operation, which could lead to excessive clamping strength and affect the safety of the operation. In addition, by setting the grooves 321, the strength of the applied resistance can be guaranteed, and the rotation of the shaft 31 can be made relatively smooth, thereby improving the stability when clamping tissue.

[0019] The inner wall of the pressure groove 32 and the sphere 322 are both magnetic, and they have the same magnetic poles.

[0020] The arc-shaped block 311 is also magnetic, and its magnetic poles are opposite to those of the sphere 322.

[0021] The magnetic poles of the arc-shaped block 311 and the inner wall of the pressure groove 32 are opposite; The magnetic repulsion between the ball 322 and the pressure groove 32 increases the force exerted by the ball 322 on the arc block 311, further increasing the resistance. The operator needs to press the movable handle 2 harder, which further improves the accuracy of tissue clamping. Furthermore, the magnetic attraction between the arc block 311 and the ball 322 pulls the ball 322, and the two are tightly attracted to each other, thereby improving the stability of the deceleration shaft 31 and ensuring the stability and smoothness of the shaft 31 during rotation.

[0022] The inner wall of the pressure groove 32 is provided with a sliding groove 325, and the two ends of the sliding groove 325 are respectively connected to the outermost and innermost grooves 321.

[0023] The groove 325 and the ball 322 fit together, and the connection between the groove 325 and the recess 321 is trapezoidal, with the two trapezoidal parts arranged opposite to each other. When the ball 322 is pushed into the last groove 321 by the arc block 311, it is pushed and slides in the trapezoidal part of the slide groove 325, thus entering the slide groove 325. Then, when the tissue is released, the torsion spring 6 generates a reaction force to reset the movable handle 2. The ball 322 slides in the slide groove 325 to the trapezoidal part at the other end and enters the first groove 321 for reset. During the reset process, the magnetic force between the inner wall of the pressure groove 32, the ball 322 and the arc block 311 slows down the reset speed of the arc block 311, thus avoiding excessive force when releasing the tissue and causing the tissue to detach from the forceps head, thus playing a protective role.

The operator holds the forceps handle and gently inserts the sampling forceps through the speculum, bringing the forceps head close to the target lesion area on the surface of the cervix. Utilizing the pre-opening characteristic of the forceps head, it is accurately placed over the target area. Step S3: Press the clamp handle, and under the action of the torsion spring 6, the upper clamp 5 is pulled closed by the slide bar 7 to cut off the target tissue block and accommodate it in the lower clamp 4; Step S4: Sample extraction and processing; Step S5: Dispose of the used disposable sampling forceps as medical waste in the designated sharps box or medical waste collection container; Step S6: Postoperative care.
