Description

Technical Field

[0001] This utility model relates to the field of joint sleeve technology, specifically an integrated, holeless locking joint sleeve. Background Technology

[0002] During arthroscopic surgery, surgeons need to operate steadily. If the puncture tube moves during the procedure, it may obstruct the field of vision or cause tissue damage. Locking prevents the puncture tube from slipping, maintaining stability. Secondly, it prevents fluid leakage. During arthroscopic surgery, fluids such as saline are used to expand the joint cavity. If there is a gap between the puncture tube and the cannula, fluid may leak out, affecting the surgical field of vision and even increasing the risk of infection. Locking ensures a tight seal and maintains fluid pressure.

[0003] Currently used articular cannulas generally have a locking function to avoid potential risks during surgery, and the locking effect is very strong. This means that the operator needs to exert force to unlock the cannula when unscrewing it, which can easily cause the cannula to shift and cause secondary damage to the patient's surgical site. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] An integrated, non-perforated locking joint cannula includes a treatment mechanism and a locking mechanism. The treatment mechanism includes a sheath, a flushing valve seat connected to the top of the sheath, a vertically slidable puncture tube passing through the sheath and the flushing valve seat, and a lock head connected to the top of the puncture tube. The locking mechanism includes a locking sleeve that is movably engaged with the top of the flushing valve seat, a positioning pin passing through the front sidewall of the locking sleeve, a limiting channel opened on the outside of the lock head and adapted for sliding connection with the positioning pin, a magnetic piece magnetically attracted to one side of the positioning pin and installed inside the limiting channel, a short shaft passing through the locking sleeve, a rubber ball connected to the inner end of the short shaft, and a slot opened on the outside of the lock head and adapted for embedding the rubber ball.

[0007] By using the above technical solution, by gripping the endoscope sheath and rotating the puncture tube in the opposite direction, the positioning pin can be separated from the magnetic plate, and then the rubber ball can be separated from the slot. The force used in the unlocking step is very small, so it will not cause the puncture tube to reposition and avoid secondary damage to the patient.

[0008] In a preferred embodiment, the present invention can be further configured such that: the diameter of the lock head is equal to the inner diameter of the lock sleeve, the outer surface of the lock head and the inner wall of the lock sleeve are both polished, and the lock head and the lock sleeve are slidably inserted into each other.

[0009] In a preferred embodiment, the present invention can be further configured such that the limiting channel and the slot are both close to the bottom of the lock head, the limiting channel is set in an "L" shape and is arranged horizontally.

[0010] In a preferred embodiment, the present invention can be further configured such that both the locating pin and the outer end of the short shaft are machined into spherical surfaces, and the diameter of the rubber ball is smaller than the diameter of the short shaft.

[0011] In a preferred embodiment, the present invention can be further configured such that a handle is fixedly attached to the top of the lock head, and the diameter of the handle is equal to the diameter of the lock head.

[0012] In a preferred embodiment, the present invention can be further configured such that recesses are provided on both sides of the handle.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, by gripping the endoscope sheath and rotating the puncture tube in the opposite direction, the positioning pin can be separated from the magnetic plate, and then the rubber ball can be separated from the slot. The force used in the unlocking step is very small, so it will not cause the puncture tube to be misaligned, thus avoiding secondary damage to the patient.

[0015] 2. In this utility model, the control sheath is aligned with and close to the patient's surgical site, and then the puncture tube is inserted into the surgical site. Then the locking head enters the locking sleeve. Here, the locking head needs to be rotated so that the positioning pin can slide into the depth of the limiting channel. Then the magnetic sheet attracts the positioning pin to achieve the initial limiting of the locking head. Then the rubber ball enters the slot to achieve the secondary limiting, thereby preventing the puncture tube from loosening and improving the stability of the instrument during use.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an integrated, holeless locking joint sleeve.

[0027] Example 1:

[0028] Combination Figure 1-4 As shown, the present invention provides an integrated non-perforated locking joint cannula, including a treatment mechanism 100 and a locking mechanism 200. The treatment mechanism 100 includes a sheath 110, a flushing valve seat 120 connected to the top of the sheath 110, a puncture tube 130 that is vertical and slides through the sheath 110 and the flushing valve seat 120, and a lock head 140 connected to the top of the puncture tube 130.

[0029] The locking mechanism 200 includes a locking sleeve 210 that is movably engaged with the top of the flushing valve seat 120, a positioning pin 220 that penetrates the front sidewall of the locking sleeve 210, a limiting channel 230 that is opened on the outside of the lock head 140 and is adapted to slide connection with the positioning pin 220, a magnetic sheet 240 that is magnetically attracted to one side of the positioning pin 220 and installed inside the limiting channel 230, a short shaft 250 that penetrates the locking sleeve 210, a rubber ball 260 that is connected to the inner end of the short shaft 250, and a slot 270 that is opened on the outside of the lock head 140 and is adapted to embed the rubber ball 260.

[0030] Furthermore, the diameter of the lock head 140 is equal to the inner diameter of the lock sleeve 210. The outer surface of the lock head 140 and the inner wall of the lock sleeve 210 are both polished. The lock head 140 and the lock sleeve 210 are slidably inserted into each other. By adopting this size and process, the lock head 140 and the lock sleeve 210 can be tightly connected, ensuring the sealing when they are connected. At the same time, it also makes the separation of the lock head 140 and the lock sleeve 210 smoother and more seamless.

[0031] Furthermore, the limiting channel 230 and the slot 270 are both close to the bottom of the lock head 140. The limiting channel 230 is set in an "L" shape and is arranged horizontally. The position design of the limiting channel 230 and the slot 270 is such that they are far away from the top of the lock sleeve 210, ensuring the sealing of the connection between the lock head 140 and the lock sleeve 210.

[0032] Example 2:

[0033] Combination Figure 1 and Figure 3 As shown, based on Embodiment 1, the outer ends of the positioning pin 220 and the short shaft 250 are both machined into spherical surfaces. The diameter of the rubber ball 260 is smaller than the diameter of the short shaft 250. The spherical design can prevent operators from being scratched by the outer ends of the positioning pin 220 or the short shaft 250 when using this instrument.

[0034] Example 3:

[0035] Combination Figure 1 As shown, in the above embodiment, a handle 300 is fixedly connected to the top of the lock head 140. The diameter of the handle 300 is equal to the diameter of the lock head 140. The handle 300 is provided to facilitate the operator to insert and remove the punch tube 130.

[0036] Furthermore, the handle 300 has notches on both sides to make it easier for the operator to grip the handle 300.

[0037] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the control sheath 110 is aligned with and close to the patient's surgical site, and then the puncture tube 130 is inserted into the surgical site. Then, the locking head 140 enters the locking sleeve 210. Here, the locking head 140 needs to be rotated so that the positioning pin 220 can slide into the depth of the limiting channel 230. Then, the magnetic sheet 240 attracts the positioning pin 220 to achieve the initial limiting of the locking head 140. Next, the rubber ball 260 enters the slot 270 to achieve secondary limiting, thereby preventing the puncture tube 130 from loosening. Then, when pulling out the puncture tube 130, the sheath 110 is gripped and the puncture tube 130 is rotated in the opposite direction to separate the positioning pin 220 from the magnetic sheet 240. Then, the rubber ball 260 separates from the slot 270. The force used in the unlocking step is very small, so it will not cause the puncture tube to reposition and avoid secondary damage to the patient.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
