Description

Technical Field

[0001] The utility model relates to the technical field of electric laparoscope cutting staplers, in particular to a clamp structure of an electric laparoscope cutting stapler. Background Art

[0002] The laparoscopic stapler (laparoscopic cutting stapler and disposable stapler magazine) is one of the important instruments in laparoscopic surgery. It replaces traditional manual suturing and uses titanium staples to separate or staple tissues. It is easy and quick to operate, greatly shortening the operation time. Different from the mechanical control of traditional manual laparoscopic staplers, electric laparoscopic staplers use power sensing to cut tissue between two staples while firing the staples. The clamp is a component on the electric laparoscopic cutting stapler used to clamp tissue.

[0003] The Chinese patent with publication number CN216570072U discloses an electric laparoscope cutting stapler clamp structure, which includes an illumination mechanism and a first clamp, and the illumination mechanism includes a groove, a first motor, a rotating rod and an illumination lamp. In the electric laparoscope cutting stapler clamp structure, the tooth plate can move left and right under the telescopic action of the electric telescopic rod, and the tooth plate can lock the first gear when it is meshed and connected with the first gear. After unlocking the first gear, the first gear can rotate, and the first clamp rotates at this time, which is convenient for adjusting the angle of the first clamp and the second clamp as a whole. Then the tooth plate moves to the right to lock the first gear. During the use of the device, the rotating rod can be rotated and unfolded, and after turning on the illumination lamp, the illumination lamp can play a role of illumination.

[0004] With respect to the above-mentioned related technologies, this structure has some shortcomings. In actual use, too many driving sources are used for driving, which results in high energy consumption and a corresponding increase in the complexity of the structure itself. Therefore, it is more prone to failure or damage, which reduces the stability during use. Due to the high complexity of the structure, more maintenance and care work is required, which increases the maintenance cost and complexity. Therefore, it is necessary to provide an electric laparoscopic cutting stapler clamp structure to solve the above-mentioned technical problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 , an embodiment provided by the utility model:

[0027] An electric laparoscope cutting stapler clamp structure, comprising:

[0028] A supporting plate 1 is provided with a groove 10 on one side of the supporting plate 1, a transmission shaft 16 is rotatably installed inside the groove 10, a first clamp 2 is fixedly sleeved on the outer wall of the transmission shaft 16, a second fixed groove 14 is provided on one side of the first clamp 2, and the transmission shaft 16 passes through the interior of the second fixed groove 14, a symmetrically distributed fixed block 8 is fixedly installed on one side of the top of the first clamp 2, a rotating shaft 11 is rotatably installed between the two fixed blocks 8, a second clamp 3 is fixedly installed on the outer wall of the rotating shaft 11, a first angle adjustment mechanism is provided on one side of the top of the first clamp 2, a mounting groove 4 is provided on one side of the top of the supporting plate 1, and a second angle adjustment mechanism is provided inside the mounting groove 4.

[0029] A cover plate 5 is provided at the top opening of the installation groove 4, and elastic metal sheets 17 are fixedly installed below both sides of the cover plate 5. A clamping groove 18 is provided above both sides of the inner wall of the installation groove 4, and the clamping groove 18 is elastically clamped with the elastic metal sheet 17.

[0030] In one embodiment, the first angle adjustment mechanism includes a first fixed groove 12, and the first fixed groove 12 is opened on one side of the top of the first clamp 2, a connecting rod 9 is fixedly installed on the outer wall of the rotating shaft 11, an electric telescopic rod 13 is hinged at the bottom of the inner wall of the first fixed groove 12, and the driving end of the electric telescopic rod 13 is hinged to the outer wall of one end of the connecting rod 9, and the electric telescopic rod can achieve slight angle adjustments through precise electric control, thereby providing higher angle adjustment accuracy and improving the accuracy of the clamp when in use.

[0031] In one of the preferred embodiments, the second angle adjustment mechanism includes a motor 6, and the motor 6 is fixedly installed inside the mounting groove 4, a worm 7 is fixedly installed on the driving end of the motor 6, and one end of the worm 7 passes through one side of the inner wall of the mounting groove 4 and extends to the inside of the groove 10, and the worm 7 is meshed with the worm wheel 15.

[0032] In one of the embodiments, one side of the inner wall of the first fixed groove 12 is arc-shaped, and the origin of one side of the inner wall of the first fixed groove 12 coincides with the rotating shaft 11. When the unfolding angle of the second clamp 3 is adjusted, the rotation of the connecting rod 9 will not collide with the inner wall of the first fixed groove 12, thereby improving the stability of the angle adjustment of the second clamp 3.

[0033] In one preferred embodiment, the connection between the cover plate 5 and the mounting slot 4 is stepped, so that the cover plate 5 and the top opening of the mounting slot 4 are closed very tightly and fit together, forming a tight sealing state. This tight connection helps prevent dust, foreign matter, etc. from entering the interior of the mounting slot 4, thereby protecting the safety of the motor 6 and other maintenance components.

[0034] The working principle of the utility model is as follows: the electrical components appearing in the present application are all externally connected to a power supply and a control switch when in use, and the parts not involved in the device are the same as the prior art or can be implemented by the prior art. When the clamp is in use, the motor 6 is first controlled by the switch to start working, and the driving end of the motor 6 drives the worm 7 to rotate, and the worm 7 is meshed with the worm wheel 15, so that the worm wheel 15 drives the transmission shaft 16 to rotate, and the rotation of the transmission shaft 16 drives the first clamp 2 to rotate, and the rotation of the first clamp 2 drives the second clamp 3 to rotate through the fixed block 8 shaft 11, so as to achieve the effect of adjusting the clamp angle, and at the same time, the electric telescopic rod 13 can be controlled by the switch to start working, and the extension of the driving end of the electric telescopic rod 13 drives the shaft 11 to rotate through the connecting rod 9, and the rotation of the shaft 11 drives the second clamp 3 to rotate, and the second clamp 3 is adjusted. After the angle of the clamp 3 and the first clamp 2 is adjusted and aligned with the tissue, the second clamp 3 is automatically closed by the drive of the electric telescopic rod 13, which is convenient for clamping the tissue and then releasing the tissue after the suturing operation is completed. When the structure is in use, the worm gear 15 and the worm 7 adjust the clamp angle through the meshing effect. At the same time, due to the self-locking nature of the worm gear, it can maintain a high stability after adjustment. During use, no additional electric self-locking structure is required. The structure uses fewer driving sources, so the energy consumption is low. In addition, since the structure itself adopts a relatively simple driving method, its complexity and the risk of failure and damage are also reduced accordingly, so it has high stability and practicality. Such a design scheme reduces the complexity of the structure and facilitates the subsequent maintenance work. Therefore, the structure has a wide range of applications and high practical value.

[0035] When performing maintenance on the clamp structure, the cover plate 5 located at the top opening of the mounting slot 4 can be directly pressed to remove the cover plate 5, which is convenient for maintaining the motor 6 inside the mounting slot 4. The cover plate 5 is fixed to the top opening of the mounting slot 4 through the elastic clamping connection between the elastic metal sheet 17 and the clamping slot 18. It can be firmly fixed to the top opening of the mounting slot 4 to ensure its stability, and it is very convenient to disassemble it, which effectively reduces the difficulty and complexity of maintenance, improves the reliability and stability of the clamp structure, and makes daily maintenance work more convenient in production use.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
