Description

TECHNICAL FIELD

[0002] As a minimally invasive surgical technique, breast endoscopic surgery has been widely used in the treatment of breast tumor resection and related diseases. Due to the lack of naturally occurring interstitial spaces in the breast region, surgical operations need to be performed in a narrow space, which puts high requirements on the fineness and controllability of surgical instruments. As a key instrument in the surgery, the core technical idea of the forceps is to optimize the structure and function systematically, so as to better adapt to the special operating environment of breast endoscopic surgery, thereby improving the accuracy and safety of the surgery. The forceps commonly used in current clinical practice are mostly modified versions of other endoscopic surgical instruments, such as laparoscopic separating forceps or gallbladder forceps. Although such instruments can achieve basic tissue clamping functions, they still have obvious shortcomings when dealing with breast endoscopic surgery.

[0003] On the one hand, the existing forceps have poor flexibility in limited space, and most products are still designed mainly for right-hand operation, increasing the complexity of surgical operation; on the other hand, they are prone to slipping when clamping breast benign tumors with tough texture and smooth surface, seriously affecting the efficiency of the surgery. In addition, due to insufficient consideration of the anatomical characteristics of breast tissue, traditional forceps are prone to cause unnecessary damage to the surrounding normal tissue during operation.

[0004] Based on the technical development of breast endoscopic reconstruction surgery by axillary approach with inflation reverse sequence method, the present inventors are committed to developing a high-performance forceps specifically for this surgical procedure to meet the actual operational needs of surgeons in the new surgical environment.

[0026] In one embodiment, with reference to the drawings attached Figures 1 to 5 The breast endoscopic reconstruction surgery forceps provided by the present application comprises a handle 1, a forceps rod 2 and a forceps head 3, the handle 1 is a reverse hand holding structure; the forceps rod 2 is connected with the handle 1 and can rotate 360° relative to the handle 1; the forceps head 3 is hinged with the end of the forceps rod 2 away from the handle 1 through a connecting rod 31, the connecting rod 31 drives the forceps head 3 to be able to deflect 0-50 degrees relative to the axial direction of the forceps rod 2, and the occlusal surface of the forceps head 3 is provided with a rat-tooth structure; a control assembly 4 is arranged on the handle 1 and connected with the forceps rod 2 and the forceps head 3 respectively, for controlling the actions of the forceps rod 2 and the forceps head 3.

[0027] The operation performance and safety in a narrow surgical space are significantly improved in the embodiment. The reverse-hand holding handle 1 enables the operator to perform fine operations in a more natural and stable posture, effectively reducing fatigue caused by long-time surgery. The clamp rod 2 can realize full circumferential rotation, and the clamp head 3 has multi-angle deflection capability, which greatly enhances the flexibility and accessibility of the instrument, enabling the doctor to easily cope with tissues of different angles and depths, and effectively avoiding the obstruction of the instrument rod to the surgical field. The mouse-tooth structure arranged on the clamp head clamping surface significantly enhances the stability of clamping and effectively prevents the slipping of soft or smooth tissues. The control assembly 4 integrated in the handle 1 realizes centralized and intuitive control of the rotation of the clamp rod 2, the deflection of the clamp head 3 and the opening and closing action, enabling the operator to complete various complex operations with one hand and improving the smoothness and efficiency of the surgery.

[0028] In some embodiments, reference is made to the drawings attached hereto Figure 2 、 Figure 3 , the control assembly 4 includes a first knob 41, a second knob 42 and a holding part 43. The first knob 41 is connected with the clamp rod 2 through a first transmission mechanism, for controlling the 360° rotation of the clamp rod 2 around its own axis. The second knob 42 is connected with the clamp head 3 through a second transmission mechanism, for controlling the deflection angle of the connecting rod 31 within the range of 0 to 50 degrees. The holding part 43 is connected with the clamp head 3 through a third transmission mechanism, for driving the opening and closing action of the clamp head 3 to grip or release the tissue. By respectively arranging the first knob 41 and the second knob 42, the operator can accurately and independently control the overall rotation of the clamp rod 2 and the multi-angle deflection of the clamp head 3 with one hand, and the two operations do not interfere with each other, greatly enhancing the flexibility of the spatial position of the instrument tip in a narrow lumen. The holding part 43 directly drives the opening and closing of the clamp head 3 in a natural way consistent with the force of the hand, realizing the quick response and reliable execution of the gripping and releasing action. The entire control system integrates the three core functions of rotation, deflection and gripping on the handle, with compact structure and clear logic, significantly reducing the complexity and learning threshold of the surgical operation, enabling the doctor to focus more on the surgery itself, thereby improving the smoothness, accuracy and efficiency of the overall operation.

By arranging the first arc-shaped slot 11 and the second arc-shaped slot 12 on the distal end and the proximal end of the handle 1 respectively, and cooperating with the gripping part 43, stable and comfortable hand support is provided for the operator holding the handle 1 with the opposite hand, and fatigue of long-time operation is effectively reduced. The first knob 41 and the second knob 42 are arranged on the upper end of the handle 1, which ensures that when the operator holds the handle 1 with the opposite hand, the thumb can naturally cover and directly operate the two knobs, so that the operator does not need to change the holding posture or move the wrist, and only the thumb tip can independently and accurately control the rotation of the clamp rod 2 and the deflection of the clamp head 3, greatly improving the convenience, reaction speed and overall control precision of the operation.

[0030] In some embodiments, with reference to the drawings attached Figure 3 , the first transmission mechanism includes a driving gear 411, a first transmission gear 412, a transmission rod 413, a second transmission gear 414 and a driven gear 415; the driving gear 411 is coaxially fixedly connected with the first knob 41, the transmission rod 413 is rotatably arranged in the handle 1, the first transmission gear 412 is fixed to one end of the transmission rod 413 and engaged with the driving gear 411; the second transmission gear 414 is fixed to the other end of the transmission rod 413, and the driven gear 415 is fixed to the end of the clamp rod 2 and engaged with the second transmission gear 414; by rotating the first knob 41, power is transmitted to the driven gear 415 through the driving gear 411, the first transmission gear 412, the transmission rod 413 and the second transmission gear 414 in sequence, to drive the clamp rod 2 to rotate 360° around its own axis.

[0031] In this embodiment, the first transmission mechanism adopts a multi-stage gear transmission system to realize accurate and reliable control of the rotary motion of the clamp rod 2; by rotating the first knob 41, power is transmitted through a series of gear pairs in stages, and finally the clamp rod 2 is stably driven to rotate 360° around its own axis; this transmission design not only ensures accurate response, but also significantly enhances the stability and controllability of the rotation process, so that the operator can easily and carefully adjust the circumferential position of the instrument tip in a small surgical space, greatly improving the flexibility and graspability of the surgical operation. Of course, the first transmission mechanism can also use a flexible shaft transmission mechanism, such as winding a flexible metal core wire on the reel of the knob; or a worm gear transmission mechanism, etc.

[0032] In some embodiments, with reference to the drawings attached Figure 3, the second transmission mechanism includes a cam 421, a slider 422, a swing lever 423, a deflection control rod 424 and a joint 425; the cam 421 is coaxially fixedly connected with the second knob 42, the slider 422 is slidably arranged in the handle 1 and is adapted to the profile of the cam 421; one end of the swing lever 423 is hingedly connected with the slider 422, and the other end is hingedly connected with the proximal end of the deflection control rod 424; the deflection control rod 424 is accommodated in the pliers rod 2, and the distal end thereof is hingedly connected with the end of the pliers head 3 through the joint 425; by rotating the second knob 42, the cam 421 is driven to rotate, the slider 422 is driven to move linearly, the swing lever 423 is driven to swing, and the movement is transmitted to the joint 425 through the deflection control rod 424, so that the connecting rod 31 is controlled to deflect around the hinge point in a range of 0 to 50 degrees.

[0033] In the embodiment, the second transmission mechanism is a cam linkage mechanism, which converts the rotary motion of the second knob 42 into the multi-angle deflection of the pliers head 3, so that the operator can intuitively and finely control the deflection angle of the pliers head in a predetermined range through simple knob operation, greatly enhances the operation ability of coping with complex angles and deep tissues in a narrow surgical space, and improves the adaptability and precision of operation. Of course, the second transmission mechanism can also use a pull rope control mechanism, a linkage mechanism or the like to realize the deflection of the pliers head 3.

[0035] In the embodiment, the third transmission mechanism uses a linkage mechanism to directly convert the hand holding action into the opening and closing operation of the pliers head 3; when the holding part 43 is pressed, the pliers head 3 is rapidly opened through the cooperative movement of the pull rod 431 and the opening and closing control rod 432; when the holding part 43 is released, the pliers head 3 can stably and reliably close under the action of the reset mechanism, so as to realize the firm holding of the tissue; the structure improves the directness and feedback feeling of operation, so that the operator can accurately control the clamping force and timing, enhances the operation confidence and operation efficiency in the operation, and avoids the possible failure risk caused by the complex structure.

[0036] In some embodiments, reference is made to the accompanying drawingsFigure 5 The forceps head 3 comprises a connecting rod 31, a first clamping jaw 32 and a second clamping jaw 33. The proximal end of the connecting rod 31 is connected to the distal end of the forceps rod 2 through the joint sheet 425, and the opening and closing joint 433 at the distal end is respectively hinged to the first clamping jaw 32 and the second clamping jaw 33 through the pin shaft 4331.

The mutual engagement of the first tooth part 322 and the second tooth part 332 further improves the stability of the gripping, so that the forceps head 3 can firmly hold the tissue without displacement. The use of the double occlusion structure improves the controllability and safety of the surgical operation, so that the operator can be more efficient when performing fine separation or traction operation.
