Description

Technical Field

[0001] The present invention and the technical field of medical equipment particularly relate to a separate uterine forceps. Background Art

[0002] In gynecological surgery, doctors use uterine graspers to fix the position of the uterus to prevent it from moving during surgery. The uterine grasper consists of a handle, a connecting rod, and a grasper head. The doctor operates the handle to make the grasper head clamp the uterus. However, in subsequent surgical steps, the handle and the connecting rod will block the surgical field of view. This visual obstruction affects the doctor's direct observation of the surgical area, increasing the difficulty and complexity of subsequent surgical steps.

[0003] Existing uterine grasping forceps have a technical problem that the handle and the connecting rod block the surgical field, which increases the difficulty and complexity of subsequent surgical steps. Summary of the invention

[0004] The object of the present invention is to provide a separate uterine forceps to solve the technical problem in the related art that the handle and the connecting rod block the surgical field, which increases the difficulty and complexity of subsequent surgical steps.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is:

[0006] The separate uterine forceps provided by the present invention comprises:

[0001] A fixing clamp, an operating clamp and a towing rope, wherein the fixing clamp comprises a first clamp arm, a second clamp arm and a locking mechanism, and the first clamp arm and the second clamp arm are hinged. The operating clamp comprises a hinged first clamp arm and a second clamp arm, and the first clamp arm and the second clamp arm are detachably connected to the first clamp arm and the second clamp arm respectively, and are used to control the clamping angle of the first clamp arm and the second clamp arm. The locking mechanism is used to lock the clamping angle of the first clamp arm and the second clamp arm. One end of the towing rope is connected to the fixing clamp.

[0002] Specifically, the locking mechanism includes a positioning block and a snap-fit ​​block, and the positioning block and the snap-fit ​​block are respectively mounted on the first clamping arm and the second clamping arm. The positioning block and the snap-fit ​​block are respectively provided with a plurality of mutually corresponding saw teeth on the opposite surfaces, and the saw teeth are engaged with each other to realize the snap-fit ​​connection between the positioning block and the snap-fit ​​block, so as to limit the rotation of the first clamping arm and the second clamping arm in the direction of increasing the included angle. The saw teeth are also provided with a guiding inclined surface, so as to prevent the first clamping arm and the second clamping arm from rotating in the direction of decreasing the included angle.

[0003] Specifically, it also includes a forced unlocking mechanism, which includes a sliding bolt slidably connected to the second clamping arm. The sliding bolt is provided with a transmission slope, and the transmission slope abuts against the engaging block. The sliding of the sliding bolt along its own axis is used to apply a thrust to the engaging block through the transmission slope to drive the engaging block to disengage from the positioning block so that the fixing clamp is switched from the clamping state to the unlocking state. In the clamping state, the first clamping arm and the second clamping arm can only rotate in the direction of reducing the angle. In the unlocking state, the first clamping arm and the second clamping arm can rotate freely.

[0004] Specifically, the fixing clamp further includes a torsion spring, which is arranged at a hinge point between the first clamping arm and the second clamping arm; the elastic force of the torsion spring is used to drive the first clamping arm and the second clamping arm to rotate in a direction in which the angle is enlarged.

[0005] Specifically, the fixing clamp further includes a fastening screw, and the first clamping arm is provided with an arc groove, and the arc groove is coaxial with the hinge axis of the first clamping arm and the second clamping arm. The fastening screw passes through the arc groove and is threadedly connected with the second clamping arm. The arc groove is used to limit the maximum angle between the first clamping arm and the second clamping arm.

[0006] Specifically, the locking mechanism further comprises a return spring, which is mounted on one end of the engaging block away from the positioning block. The engaging block is slidably connected to the second clamping arm along the hinge axis direction of the first clamping arm and the second clamping arm. The two ends of the return spring are respectively in contact with the engaging block and the second clamping arm, and are used to apply a thrust to the engaging block so that the engaging block is in contact with the positioning block.

[0007] Specifically, the operating pliers further comprises a pulling handle, the pulling handle is slidably connected to the second pliers arm and is detachably connected to the forced unlocking mechanism, the pulling handle slides along the second pliers arm to switch the operating pliers between the first posture and the second posture, thereby driving the fixed clamp to switch the state. In the first posture, the fixed clamp is in a clamped state. In the second posture, the fixed clamp is in an unlocked state. The rotation of the first pliers arm and the second pliers arm around the hinge axis is used to push the first clamping arm and the second clamping arm to rotate in the direction of reducing the angle.

[0008] Specifically, the pulling handle includes a connecting rod, a plug cone and a pull ring, and the connecting rod is slidably connected to the second clamp arm. The forced unlocking mechanism also includes a sleeve ring, and the sleeve ring is installed at the end of the sliding bolt away from the transmission inclined surface. The pull ring and the plug cone are respectively arranged at both ends of the connecting rod, and the plug cone is plugged into the sleeve ring. The pull ring is used to drive the connecting rod to slide along the second clamp arm so that the plug cone drives the sleeve ring and thus drives the sliding bolt to slide along its own axis direction, thereby controlling the fixing clamp to switch between the clamping state and the unlocking state.

[0009] Specifically, the first clamp arm is provided with a buckle on the fitting surface with the first clamp arm, which is used to engage with the groove corresponding to the first clamp arm, so as to achieve a detachable connection between the first clamp arm and the second clamp arm. The second clamp arm is provided with a buckle on the fitting surface with the second clamp arm, which is used to engage with the groove corresponding to the second clamp arm, so as to achieve a detachable connection between the second clamp arm and the second clamp arm.

[0010] Specifically, the hinge axis of the first clamp arm and the second clamp arm is parallel to the hinge axis of the first clamp arm and the second clamp arm. The buckles are all configured as cylinders parallel to the hinge axis of the first clamp arm and the second clamp arm. The groove corresponds to the buckle shape.

[0007] Based on the above technical solutions, the beneficial effects of the present invention are analyzed as follows:

[0008] The present invention provides a separate uterine forceps, comprising:

[0011] A fixing clamp, an operating clamp and a towing rope, wherein the fixing clamp comprises a first clamp arm, a second clamp arm and a locking mechanism, and the first clamp arm and the second clamp arm are hinged. The operating clamp comprises a hinged first clamp arm and a second clamp arm, and the first clamp arm and the second clamp arm are detachably connected to the first clamp arm and the second clamp arm respectively, and are used to control the clamping angle of the first clamp arm and the second clamp arm. The locking mechanism is used to lock the clamping angle of the first clamp arm and the second clamp arm. One end of the towing rope is connected to the fixing clamp.

[0009] In specific application, the head end of the towing rope is connected to the fixing clamp. After the fixing clamp is docked with the operating forceps, the fixing clamp is sent into the patient's abdominal cavity in a closed state of minimum size through the operating forceps. At this time, the end of the towing rope extends out of the abdominal cavity. After the fixing clamp is opened in the abdominal cavity, the angle between the first clamp arm and the second clamp arm is controlled by the clamping of the first clamp arm and the second clamp arm to bite the uterine tissue. The locking mechanism locks the first clamp arm and the second clamp arm at the current clamping angle to lock the fixing clamp with the uterine tissue. The operating forceps are separated from the first clamp arm and the second clamp arm and pulled out of the abdominal cavity. The towing rope is used to lift the uterine tissue.

[0010] It can be seen that compared with the prior art, the detachable uterine forceps avoids the obstruction of the field of vision of subsequent surgical steps by providing the detachably connected fixing clamp and the operating clamp, and by separating the operating clamp after the fixing clamp bites the uterine tissue and locks it. The technical problem of the existing uterine grasping forceps that the handle and the connecting rod obstruct the surgical field of vision, which increases the difficulty and complexity of the subsequent surgical steps, is overcome.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are sub-embodiments of the present invention, rather than the embodiments of the whole block. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0031] Existing uterine grasping forceps have a technical problem that the handle and the connecting rod block the surgical field, which increases the difficulty and complexity of subsequent surgical steps.

[0032] In view of this, the present invention provides a separate uterine forceps, comprising:

[0012] The fixed clamp 100, the operating clamp 200 and the towing rope 300, the fixed clamp 100 includes a first clamp arm 110, a second clamp arm 120 and a locking mechanism 130, the first clamp arm 110 and the second clamp arm 120 are hinged. The operating clamp 200 includes a hinged first clamp arm 210 and a second clamp arm 220, the first clamp arm 210 and the second clamp arm 220 are detachably connected to the first clamp arm 110 and the second clamp arm 120, respectively, for controlling the clamping angle of the first clamp arm 110 and the second clamp arm 120. The locking mechanism 130 is used to lock the clamping angle of the first clamp arm 110 and the second clamp arm 120. One end of the towing rope 300 is connected to the fixed clamp 100.

[0033] Based on the above technical solutions, the separate uterine forceps provided by the present invention can achieve the following technical effects:

[0034] The detachable uterine forceps is provided with a detachably connected fixing clamp 100 and an operating clamp 200, and the operating clamp 200 is separated after the fixing clamp 100 bites the uterine tissue and locks it, thereby avoiding the obstruction of the field of vision of the subsequent surgical steps. The technical problem of the existing uterine grasping forceps that the handle and the connecting rod obstruct the surgical field, which increases the difficulty and complexity of the subsequent surgical steps, is overcome.

[0035] The following combination Figures 1 to 11 The structure and shape of the separate uterine clamp provided in this embodiment are described in detail:

[0013] Regarding the structural composition of the locking mechanism 130, specifically:

[0014] The locking mechanism 130 includes a positioning block 131 and a snap-fit ​​block 132, and the positioning block 131 and the snap-fit ​​block 132 are respectively mounted on the first clamping arm 110 and the second clamping arm 120. A plurality of mutually corresponding saw teeth 1311 are respectively arranged on the opposite surfaces of the positioning block 131 and the snap-fit ​​block 132, and the saw teeth 1311 are engaged with each other to realize the engagement of the positioning block 131 and the snap-fit ​​block 132, so as to limit the rotation of the first clamping arm 110 and the second clamping arm 120 in the direction of increasing the included angle. The saw teeth 1311 are also provided with a guiding inclined surface 101, so as to avoid the rotation of the first clamping arm 110 and the second clamping arm 120 in the direction of decreasing the included angle. The saw teeth 1311 are a one-way tooth structure similar to a ratchet. Since the clamping angle of the first clamping arm 110 and the second clamping arm 120 can only change in the direction of decreasing the included angle, after the operating forceps 200 are separated from the fixing clamp 100, the fixing clamp 100 can still remain in the state of biting the uterine tissue.

[0015] How the fixing clip 100 is released from the clamping state is described in detail as follows:

[0016] The clamp 100 further includes a forced unlocking mechanism 140, which includes a sliding bolt 141 slidably connected to the second clamping arm 120. The sliding bolt 141 is provided with a transmission inclined surface 102, and the transmission inclined surface 102 abuts against the engaging block 132. The sliding of the sliding bolt 141 along its own axis is used to apply a thrust to the engaging block 132 through the transmission inclined surface 102 to drive the engaging block 132 to disengage from the positioning block 131 so that the fixing clamp 100 switches from the clamping state to the unlocking state. In the clamping state, the first clamping arm 110 and the second clamping arm 120 can only rotate in the direction of reducing the angle. In the unlocking state, the first clamping arm 110 and the second clamping arm 120 can rotate freely.

[0017] How the first clamping arm 110 and the second clamping arm 120 achieve angle expansion in the unlocked state is described in detail as follows:

[0018] The fixing clamp 100 also includes a torsion spring 150, which is arranged at the hinge point of the first clamping arm 110 and the second clamping arm 120; when the fixing clamp 100 is in an unlocked state, the elastic force of the torsion spring 150 is used to drive the first clamping arm 110 and the second clamping arm 120 to rotate in the direction of increasing the angle.

[0019] How does the fixing clamp 100 prevent the first clamping arm 110 and the second clamping arm 120 from excessively expanding the included angle under the elastic force of the torsion spring 150? Specifically:

[0020] The fixing clamp 100 further includes a fastening screw 160. The first clamping arm 110 is provided with an arc groove 103, which is coaxial with the hinge axis of the first clamping arm 110 and the second clamping arm 120. The fastening screw 160 passes through the arc groove 103 and is threadedly connected to the second clamping arm 120. The arc groove 103 is used to limit the maximum angle between the first clamping arm 110 and the second clamping arm 120.

[0021] In the solution of this embodiment, the locking mechanism 130 further includes a return spring 133, which is installed at one end of the engaging block 132 away from the positioning block 131. The engaging block 132 is slidably connected to the second clamping arm 120 along the hinge axis direction of the first clamping arm 110 and the second clamping arm 120. Both ends of the return spring 133 abut against the engaging block 132 and the second clamping arm 120, respectively, for applying a thrust to the engaging block 132 so that the engaging block 132 abuts against the positioning block 131.

[0022] Regarding how the operating forceps 200 triggers the forced unlocking mechanism 140, specifically:

[0023] The operating pliers 200 further includes a pulling handle 230 and a gripping handle 240. The first pliers arm 210 and the second pliers arm 220 are both provided with a gripping handle 240 at one end away from the fixed clamp 100, so as to facilitate applying force to the first pliers arm 210 and the second pliers arm 220. The rotation of the first pliers arm 210 and the second pliers arm 220 around the hinge axis is used to push the first clamping arm 110 and the second clamping arm 120 to rotate in a direction in which the angle is reduced. The pulling handle 230 is slidably connected to the second pliers arm 220 and is detachably connected to the forced unlocking mechanism 140. The pulling handle 230 slides along the second pliers arm 220 to switch the operating pliers 200 between the first posture and the second posture, thereby driving the fixed clamp 100 to switch states. In the first posture, the fixed clamp 100 is in a clamped state. In the second posture, the fixed clamp 100 is in an unlocked state.

[0024] Regarding the structural composition of the pulling handle 230, specifically:

[0025] The pulling handle 230 includes a connecting rod 231, a plug cone 232 and a pull ring 233. The connecting rod 231 is slidably connected to the second clamp arm 220. The forced unlocking mechanism 140 also includes a sleeve ring 142, which is installed at the end of the sliding bolt 141 away from the transmission inclined surface 102. The pull ring 233 and the plug cone 232 are respectively arranged at both ends of the connecting rod 231, and the plug cone 232 is plugged into the sleeve ring 142. The pull ring 233 is used to drive the connecting rod 231 to slide along the second clamp arm 220 so that the plug cone 232 drives the sleeve ring 142 and drives the sliding bolt 141 to slide along its own axis direction, thereby controlling the fixing clamp 100 to switch between the clamping state and the unlocking state.

[0026] How the operating clamp 200 is docked with the fixing clamp 100 is described in detail as follows:

[0027] The first clamp arm 210 is provided with a buckle 211 on the surface in contact with the first clamp arm 110, which is used to engage with the groove 104 corresponding to the first clamp arm 110, so as to achieve a detachable connection between the first clamp arm 210. The second clamp arm 220 is provided with a buckle 211 on the surface in contact with the second clamp arm 120, which is used to engage with the groove 104 corresponding to the second clamp arm 120, so as to achieve a detachable connection between the second clamp arm 220 and the second clamp arm 120. When the second clamp arm 220 is connected to the second clamp arm 120, the sliding movement of the pulling handle 230 relative to the second clamp arm 220 is equivalent to the movement of the pulling handle 230 relative to the second clamp arm 120, thereby pulling the sliding bolt 141.

[0028] Furthermore, the hinge axis of the first clamp arm 210 and the second clamp arm 220 is parallel to the hinge axis of the first clamp arm 110 and the second clamp arm 120. The buckle 211 is configured as a cylinder parallel to the hinge axis of the first clamp arm 110 and the second clamp arm 120. The groove 104 corresponds to the shape of the buckle 211. When the first clamp arm 110 and the second clamp arm 120 form any angle, the cylindrical wall of the buckle 211 can be clamped in the groove 104 to achieve a stable connection.

[0036] In summary, the specific working process of the separate uterine clamp provided in this embodiment is as follows:

[0037] Take the example that the initial state of the fixing clamp 100 is the clamping state and the initial state of the operating forceps 200 is the first posture.

[0038] After the first end of the towing rope 300 is connected to the fixing clamp 100 and the buckle 211 of the fixing clamp 100 is connected to the groove 104 of the operating forceps 200, the fixing clamp 100 is sent into the patient's abdominal cavity in a closed state of the minimum size through the operating forceps 200. At this time, the end of the towing rope 300 extends out of the abdominal cavity.

[0039] Pulling the pull ring 233 drives the connecting rod 231 to slide along the second clamp arm 220, thereby driving the plug cone 232 to drive the sleeve ring 142 and then drive the sliding bolt 141 to slide along its own axial direction to make the locking block 132 disengage the positioning block 131, and the fixing clamp 100 switches from the clamping state to the unlocking state.

[0040] The elastic force of the torsion spring 150 drives the first clamping arm 110 and the second clamping arm 120 to open in the abdominal cavity, and then the first clamping arm 210 and the second clamping arm 220 are clamped to control the angle between the first clamping arm 110 and the second clamping arm 120 to decrease so as to bite the uterine tissue.

[0041] The pull ring 233 is pulled in the reverse direction to drive the connecting rod 231 to slide along the second clamp arm 220, thereby driving the plug cone 232 to drive the sleeve ring 142 and then drive the sliding bolt 141 to slide along its own axis direction so that the clamping block 132 abuts against the positioning block 131 under the elastic force of the return spring 133, and the fixing clamp 100 switches from the unlocked state to the clamped state. At this time, the first clamping arm 110 and the second clamping arm 120 are locked at the current clamping angle to lock the fixing clamp 100 with the uterine tissue.

[0042] The operating forceps 200 are separated from the first clamping arm 110 and the second clamping arm 120 and withdrawn from the abdominal cavity. Pulling the towing rope 300 outside the abdominal cavity can be used to pull up the uterine tissue.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for the block-by-block or full-block technical features therein. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
