Description

Technical Field

[0001] This utility model relates to the field of thermal biopsy forceps technology, specifically to a disposable thermal biopsy forceps with anti-adhesion feature. Background Technology

[0002] A thermal biopsy forceps is a medical device primarily used for the diagnosis and treatment of tissue lesions. It utilizes the principle of high-frequency electromagnetic waves to convert electrical energy into heat energy, thereby destroying diseased tissue through thermal action to achieve the purpose of treatment and sampling. The existing patent for disposable thermal biopsy forceps, patent publication number CN220069762U, includes a main body, a handle connector at the end of the main body, a sheath at the end of the handle connector, a sheath at the end of the sheath, and a flat-jaw forceps head at the end of the sheath. The main body consists of rod A and rod B, with one end of rod B penetrating the inner side of rod A. A limiting component is provided at the contact point between rod B and rod A, consisting of a groove and a slider. The groove is formed on the inner wall of rod A, and the slider is fixed to the surface of rod B. Through the designed fixing mechanism, after the handle B is pulled or pushed, it is fixed in place, eliminating the need for continuous manual operation of the handle B, increasing operational convenience. This allows for the freeing up of one hand to operate other equipment during the removal of the disposable thermal biopsy forceps after specimen collection, thus facilitating use.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: although they can be held by the handle during use, the lack of an effective steering adjustment structure means that the thermal biopsy forceps need to be manually rotated to adjust their overall direction, which is inconvenient in a confined operating space. Therefore, we proposed an anti-adhesion disposable thermal biopsy forceps to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a non-adhesive disposable thermal biopsy forceps, which solves the problem that existing thermal biopsy forceps, due to the lack of an effective steering adjustment structure, require manual rotation to adjust their overall direction during use, which is inconvenient in confined operating spaces.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: anti-adhesion disposable thermal biopsy forceps, including a gripping mechanism, wherein the main body of the gripping mechanism is a cylindrical structure with bidirectional through-holes on both the upper and lower sides, and an annular guide groove is provided on the outer peripheral surface of the gripping mechanism;

[0006] A connecting mechanism is sleeved on the outer side of the gripping mechanism. The connecting mechanism is a ring structure. A ring-shaped guide ring assembly is also fixedly connected to the inner wall of the connecting mechanism. The guide ring assembly is rotatably connected in the guide groove.

[0007] The connecting mechanism is internally rotatably connected to a clamp plate assembly, which has an arc-shaped structure. Electromagnetic ring assemblies are fixedly connected to the outer sides of both clamp plate assemblies. Heating units and anti-stick coatings are fixedly connected to the outer and inner sides of the clamp plate assemblies, respectively.

[0008] Preferably, an anti-slip component is fixedly connected to the outer peripheral surface of the gripping mechanism, and the anti-slip component has a ring structure.

[0009] Preferably, the gripping mechanism is internally rotatably connected to a guide rod mechanism, the main body of which is a cylindrical structure.

[0010] Preferably, a sealing block is fixedly connected to the top surface of the guide rod mechanism, and the sealing block has a circular cross-section.

[0011] Preferably, an adjusting block is fixedly connected to the top surface of the sealing block, and the outer peripheral surface of the adjusting block is provided with notches in a ring array.

[0012] Preferably, a push switch matching the magnetic ring assembly is fixedly connected to the top surface of the adjusting block.

[0013] Preferably, a wire harness is fixedly connected to the outer side of the sealing block, and a connecting plate matching the connecting mechanism is fixedly connected to the bottom of the outer peripheral surface of the guide rod mechanism.

[0014] Beneficial effects

[0015] This invention provides a disposable, non-adhesive thermal biopsy forceps. Compared with the prior art, it has the following advantages:

[0016] This anti-adhesion disposable thermal biopsy forceps, through the cooperation of the guide groove of the gripping mechanism and the guide ring assembly of the connecting mechanism, enables flexible steering of the biopsy forceps. In a confined operating space, medical staff can easily adjust the direction of the forceps plate assembly to accurately reach the target tissue location, greatly improving the convenience and accuracy of the operation. By setting an anti-slip component on the outer periphery of the gripping mechanism, the grip friction is effectively increased, reducing the possibility of the thermal biopsy forceps slipping during operation, avoiding accidental injury to the patient due to instrument slippage, and ensuring the safety of the surgical procedure.

[0017] This anti-adhesion disposable thermal biopsy forceps, equipped with a heating unit in the forceps plate assembly, enables stable thermal biopsy operations. Simultaneously, the anti-adhesion coating prevents tissue adhesion, ensuring the complete acquisition of tissue samples during each thermal biopsy compared to existing technologies. This improves the accuracy of diagnosis and treatment, enhancing the actual effectiveness of thermal biopsies. Furthermore, a sealing block at the top of the guide rod mechanism prevents external impurities from entering the gripping mechanism, protecting internal components such as the guide rod and connecting mechanisms, extending the instrument's lifespan, and reducing instrument malfunctions caused by internal contamination.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 6 The present invention provides a technical solution: anti-adhesion disposable thermal biopsy forceps, including a gripping mechanism 1. The main body of the gripping mechanism 1 is a cylindrical structure with bidirectional through-holes on both the upper and lower sides. A guide groove 1011 with an annular structure is provided on the outer peripheral surface of the gripping mechanism 1.

[0027] A connecting mechanism 3 is sleeved on the outer side of the gripping mechanism 1. The connecting mechanism 3 is a ring structure. A ring structure guide ring assembly 301 is also fixedly connected to the inner wall of the connecting mechanism 3. The guide ring assembly 301 is rotatably connected in the guide groove 1011.

[0028] The connecting mechanism 3 is internally rotatably connected to a clamp plate assembly 3011. The clamp plate assembly 3011 has an arc-shaped structure. The outer sides of both clamp plate assemblies 3011 are fixedly connected to a magnetic ring assembly 3012 with an electromagnet structure. The outer and inner sides of the clamp plate assembly 3011 are respectively fixedly connected to a heating unit 3013 and an anti-stick coating 3014.

[0029] The guide groove 1011 of the gripping mechanism 1 cooperates with the guide ring assembly 301 of the connecting mechanism 3, enabling the connecting mechanism 3 to rotate relative to the gripping mechanism 1, thereby achieving the adjustment of the biopsy forceps' direction. The forceps plate assembly 3011 is arc-shaped and equipped with a magnetic ring assembly 3012, a heating unit 3013, and an anti-adhesion coating 3014. The magnetic ring assembly 3012 can be used to control the opening and closing, the heating unit 3013 can perform thermal biopsy operations, and the anti-adhesion coating 3014 can prevent tissue adhesion.

[0030] See Figure 1 - Figure 5 An anti-slip component 101 is fixedly connected to the outer peripheral surface of the gripping mechanism 1. The anti-slip component 101 has a ring structure.

[0031] By setting an anti-slip component 101 on the outer peripheral surface of the gripping mechanism 1, the friction force when medical staff hold the biopsy forceps can be increased, preventing the biopsy forceps from slipping during use and improving the safety and stability of the operation.

[0032] See Figure 1 - Figure 3 The gripping mechanism 1 is internally connected to a guide rod mechanism 2, the main body of which is a cylindrical structure;

[0033] By rotating the connecting guide rod mechanism 2 inside the gripping mechanism 1, support and rotation base are provided for the subsequently connected components such as the sealing block 201 and the adjusting block 2011, ensuring the smooth operation of related tasks.

[0034] See Figure 3 - Figure 6 A sealing block 201 is fixedly connected to the top surface of the guide rod mechanism 2. The sealing block 201 has a circular cross-section.

[0035] By setting a sealing block 201 at the top of the guide rod mechanism 2, external impurities can be prevented from entering the gripping mechanism 1, protecting the internal structure and ensuring the normal operation of the instrument.

[0036] See Figure 1 - Figure 2 An adjusting block 2011 is fixedly connected to the top surface of the sealing block 201, and the outer circumferential surface of the adjusting block 2011 is provided with notches in a ring array.

[0037] By setting an adjustment block 2011 at the top of the sealing block 201, the notch on its outer periphery makes it convenient for medical staff to apply force with tools or fingers, and to rotate and adjust the adjustment block 2011.

[0038] See Figure 3 - Figure 5 A push switch 2012 that matches the magnetic ring assembly 3012 is fixedly connected to the top surface of the adjusting block 2011;

[0039] By setting a push switch 2012 at the top of the adjusting block 2011 that matches the magnetic ring assembly 3012, medical staff can control the power-on state of the magnetic ring assembly 3012 by pressing the switch 2012, thereby controlling the opening and closing of the clamp assembly 3011.

[0040] See Figure 1 - Figure 2 A wire harness 2013 is fixedly connected to the outer side of the sealing block 201, and a connecting plate 2014 matching the connecting mechanism 3 is fixedly connected to the bottom of the outer peripheral surface of the guide rod mechanism 2.

[0041] The wiring harness 2013 on the outside of the sealing block 201 is used to transmit power or signals to power components such as the heating unit 3013 or transmit control signals; the connecting plate 2014 at the bottom of the guide rod mechanism 2 matches the connecting mechanism 3 to enhance the stability of the connection between the guide rod mechanism 2 and the connecting mechanism 3.

[0042] During operation, the holding mechanism 1 is a cylindrical structure with bidirectional passage on both the upper and lower sides. An annular guide groove 1011 is provided on its outer circumference. The connecting mechanism 3 is annular, and an annular guide ring assembly 301 is fixedly connected to its inner wall. The guide ring assembly 301 is rotatably connected in the guide groove 1011. When it is necessary to adjust the direction of the thermal biopsy forceps, medical staff do not need to rotate the entire holding mechanism 1. They only need to rotate the adjusting block 2011 to drive the entire connecting mechanism 3. Due to the cooperation between the guide ring assembly 301 and the guide groove 1011, the connecting mechanism 3 can rotate smoothly relative to the holding mechanism 1, thereby driving the forceps plate assembly 3011 inside the connecting mechanism 3 to turn, so that the thermal biopsy forceps can be flexibly adjusted in direction to adapt to the needs of use in narrow operating spaces.

[0043] The guide rod mechanism 2 is rotatably connected inside the gripping mechanism 1. A sealing block 201 is fixedly connected to its top end. An adjusting block 2011 is connected to the top end of the sealing block 201. The outer circumferential surface of the adjusting block 2011 has notches arranged in a ring array to facilitate operation by medical staff. A press switch 2012 is fixedly connected to the top end of the adjusting block 2011. The press switch 2012 is matched with the electromagnet structure magnetic ring assembly 3012 on the outside of the clamp assembly 3011. When the medical staff presses the press switch 2012, the circuit is turned on, and the magnetic ring assembly 3012 generates magnetism. Utilizing the interaction of magnetism, the two clamp assemblies 3011 attract or repel each other to realize the opening and closing action, which facilitates the clamping of tissue samples.

[0044] During a thermal biopsy, power is supplied to the heating unit 3013 via the wiring harness 2013 on the outside of the sealing block 201. The heating unit 3013 then starts working, converting electrical energy into heat energy to perform a thermal biopsy on the tissue in contact with the forceps assembly 3011, destroying the diseased tissue to achieve the purpose of treatment and sampling. At the same time, the anti-adhesion coating 3014 on the inside of the forceps assembly 3011 plays a role. Due to its special material and surface characteristics, it can effectively reduce the adhesion between the tissue and the forceps, preventing the tissue from sticking to the forceps during the thermal biopsy, and ensuring the integrity and accuracy of each tissue sample taken.

[0045] The bottom of the outer periphery of the guide rod mechanism 2 is fixedly connected to the connecting plate 2014, which matches the connecting mechanism 3. The connecting plate 2014 and the connecting mechanism 3 are tightly fitted, which enhances the stability of the connection between the guide rod mechanism 2 and the connecting mechanism 3. This ensures that all components work together during operation without loosening or displacement affecting the operation. The sealing block 201 is located at the top of the guide rod mechanism 2. Its circular cross-section matches the inside of the gripping mechanism 1, which can effectively prevent external impurities, such as body fluids and tissue debris, from entering the gripping mechanism 1, avoiding contamination and damage to the internal structure and ensuring the normal operation of the instrument.

[0046] Anti-slip grip principle: An annular anti-slip component 101 is fixedly connected to the outer peripheral surface of the gripping mechanism 1. When medical staff hold the thermal biopsy forceps for operation, the anti-slip component 101 increases the friction between the hand and the gripping mechanism 1. Even if the hand is sweaty or comes into contact with body fluids during operation, which makes the surface slippery, the thermal biopsy forceps can be effectively prevented from slipping from the hand, thus improving the safety and stability of the operation.

[0047] In summary, this device can accelerate heat dissipation by using the clamp assembly 3011 with an arc-shaped structure.

[0048] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
