Description

Technical Field

[0001] The utility model relates to the technical field of thoracoscopic surgical tools, in particular to a cold light source auxiliary supporting tool for an eyepiece device of a laparoscopic surgical operation. Background Art

[0002] Advances in technology have made it possible to perform surgery through smaller incisions. This causes less tissue damage than traditional surgery. Through the keyhole-sized incision, the surgeon can insert a tiny light source, camera, and surgical instruments. The surgeon uses the images transmitted to the monitor to guide the operation of the surgical instruments. This type of surgery is called laparoscopic surgery when it is performed in the abdomen, arthroscopic surgery when it is performed in a joint, and thoracoscopic surgery when it is performed in the chest.

[0003] like Figure 3 As shown, the eyepiece device commonly used in laparoscopic surgery is composed of two parts: an eyepiece body and an external cold light source. However, the eyepiece device with this structure has the following inconveniences during actual use: during the use of the eyepiece device, the operator is required to hold the eyepiece body with one hand and the handle with the other hand, and place the cold light source between the base of the hand and the handle. Since the cold light source is supported by the hand, during the actual surgical operation, if the cold light source protrudes upward too much, it will interfere with normal surgical use. If the cold light source is bent downward excessively, it will cause the light source to fail to be normally transmitted to the eyepiece body or the cold light source will be damaged by bending.

[0004] In view of this, it is particularly important to design and manufacture an auxiliary support tool that can be detachably installed on the eyepiece device to stably limit the cold light source on the eyepiece body during the actual operation of laparoscopic surgery. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the eyepiece device used in traditional laparoscopic surgery requires the operator to keep the cold light source in his hands, which not only affects the safety of the surgical operation, but also reduces the convenience of operating the eyepiece device. A cold light source auxiliary support tool for the eyepiece device of laparoscopic surgery is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A cold light source auxiliary support tool for a laparoscopic surgical eyepiece device comprises an eyepiece body, a connecting seat fixed on the eyepiece body, a connecting tube fixed on the upper end of the connecting seat, a handle installed on one end of the eyepiece body close to the connecting seat, and a cold light source detachably installed on the connecting tube, wherein a support mechanism for limiting the cold light source and supporting it above the eyepiece body is provided between the eyepiece body, the connecting seat and the handle.

[0008] As a further description of the above technical solution:

[0009] The supporting mechanism includes an elastic buckle which is sleeved on the outside of the eyepiece body and located between the connecting seat and the handle, a supporting frame which is integrally fixed to the upper end of the elastic buckle, an arc-shaped bracket which is integrally fixed to the upper end of the supporting frame and has a semi-arc-shaped cross-section, and a binding portion which is arranged on the upper end of the arc-shaped bracket.

[0010] As a further description of the above technical solution:

[0011] A locking portion is provided between the lower end of the elastic buckle and the connecting seat.

[0012] As a further description of the above technical solution:

[0013] The locking part includes two elastic blocks symmetrically fixing the lower end of the elastic buckle, a limiting block movably installed between the connecting seat and the two elastic blocks, and a limiting clip symmetrically fixed at the right end of the limiting block and abutting against the two elastic blocks.

[0014] As a further description of the above technical solution:

[0015] A grip hole is provided in the middle of the right end of the limiting plug.

[0016] As a further description of the above technical solution:

[0017] The inner side of the elastic buckle is filled with a non-slip rubber pad that fits the outer wall of the eyepiece body.

[0018] As a further description of the above technical solution:

[0019] The binding part comprises a plurality of Velcro strips fixed at equal angles at the rear end of the arc-shaped bracket with free ends facing forward, and an adhesive layer installed at the front end of the arc-shaped bracket and corresponding to the plurality of Velcro strips.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0021] In the utility model, a detachable supporting mechanism is provided between the original eyepiece body and the cold light source, and the supporting structure is composed of four parts: an elastic buckle, a supporting frame, an arc-shaped bracket and a limiting plug-in block. The supporting mechanism can be fixedly installed between the eyepiece body, the connecting seat and the handle through the elastic buckle and the limiting plug-in block. The cold light source can be slidably buckled onto the arc-shaped bracket, and then the cold light source can be fixed on the arc-shaped bracket at multiple points using a Velcro strip. During actual use, the operator can stably maintain the working state of the cold light source by holding the handle and the elastic buckle. This structure can stably limit and support the cold light source on the eyepiece body, thereby reducing the occurrence of abnormal problems such as displacement, shaking or bending of the cold light source when operating the eyepiece device, thereby improving the safety and convenience of the operator in actually using the eyepiece device.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0028] See also Figure 1-3The utility model provides a technical solution: a cold light source auxiliary supporting tool for a laparoscopic surgical eyepiece device, comprising an eyepiece body 1, a connecting seat 101 fixed on the eyepiece body 1, a connecting tube 102 fixed at the upper end of the connecting seat 101, a handle 103 installed at one end of the eyepiece body 1 close to the connecting seat 101, and a cold light source 2 detachably installed on the connecting tube 102, and a supporting mechanism for limiting the cold light source 2 and supporting it above the eyepiece body 1 is provided between the eyepiece body 1, the connecting seat 101 and the handle 103.

[0029] Specifically, Figure 1 and Figure 2 As shown, the supporting mechanism includes an elastic buckle 3 which is sleeved on the outside of the eyepiece body 1 and located between the connecting seat 101 and the handle 103, a supporting frame 301 which is integrally fixed to the upper end of the elastic buckle 3, an arc-shaped bracket 302 which is integrally fixed to the upper end of the supporting frame 301 and has a semi-arc-shaped cross-section, and a binding portion arranged at the upper end of the arc-shaped bracket 302.

[0030] Specifically, Figure 1 and Figure 2 As shown, the binding portion includes a plurality of Velcro strips 304 fixed at equal angles at the rear end of the arc bracket 302 with the free ends facing forward, and an adhesive layer 303 installed at the front end of the arc bracket 302 and corresponding to the plurality of Velcro strips 304. After the Velcro strips 304 wrap the cold light source line 2, the free ends of the Velcro strips 304 can be bonded to the adhesive layer 303, so that the cold light source line 2 is bundled and fixed on the arc bracket 302.

[0031] Specifically, Figure 1 and Figure 2 As shown, a locking part is arranged between the lower end of the elastic buckle 3 and the connecting seat 101, and the locking part includes two spring blocks 305 symmetrically fixed to the lower end of the elastic buckle 3, a limiting plug block 4 movably installed between the connecting seat 101 and the two spring blocks 305, and a limiting clip 401 symmetrically fixed to the right end of the limiting plug block 4 and abutting against the two spring blocks 305. When the two limiting clips 401 on the limiting plug block 4 slide between the two spring blocks 305 of the elastic buckle 3, the lower end of the elastic buckle 3 can be locked inward, thereby enhancing the locking force of the elastic buckle 3 locked on the eyepiece body 1, and preventing the elastic buckle 3 from rotating and displacing on the eyepiece body 1. Among them, a grip hole 402 is opened in the middle part of the right end of the limiting plug block 4, which is convenient for the operator to insert his hand into the limiting plug block 4, and drive the limiting clip 401 part of the limiting plug block 4 to slide between the spring blocks 305 of the elastic buckle 3.

[0032] Specifically, Figure 2As shown, the inner side of the elastic buckle 3 is filled with a non-slip rubber pad 5 that fits the outer wall of the eyepiece body 1. On the one hand, it can prevent the elastic buckle 3 from directly rigidly sticking out of the outer wall of the eyepiece body 1, reducing the rigid contact damage of the elastic buckle 3 to the eyepiece body 1. On the other hand, it improves the contact friction between the elastic buckle 3 and the eyepiece body 1, which can prevent the elastic buckle 3 from rotating and displacing on the eyepiece body 1.

[0033] Working principle: When in use, first, the operator can direct and buckle the elastic buckle 3 into the gap between the eyepiece body 1, the connecting seat 101 and the handle 103, and then adjust the position of the support frame 301 to keep it parallel to the connecting tube 102. Secondly, the operator can take the limiting plug 4, abut the upper end of the limiting plug 4 with the lower end of the connecting seat 101, and then slide the limiting clip 401 on the limiting plug 4 between the two elastic plug blocks 305 of the elastic buckle 3. At this time, the elastic buckle 3 will be stably fixed on the eyepiece body 1 under the combined action of the anti-slip rubber pad 5 and the buckle lock of the limiting plug 4. After the cold light source line 2 is slid onto the arc-shaped bracket 302, the Velcro strip 304 can be wrapped forward to cover the cold light source line 2 and then bonded to the adhesive layer 303. At this time, the cold light source line 2 is limitedly supported on the arc-shaped bracket 302. During actual use, the operator holds the eyepiece body 1 with one hand and the handle 103, the elastic buckle 3 and the support frame 301 with the other hand, and buckles the cold light source line 2 between the base of the hand and the handle 103. At this time, the cold light source line 2 is displaced, shaken or bent during use, which reduces the interference with laparoscopic surgery and improves the safety and stability of the eyepiece device.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
