Description

Technical Field

[0001] The utility model relates to the technical field of surgical instruments, in particular to a split scalp retractor. Background Art

[0002] Scalp retractors play an important role in surgery. Scalp retractors are used to pull and fix the scalp. The head of the retractor should have good elasticity and firmness. In addition to the sharp tip, the surface of the retractor should not have sharp edges, burrs, or cracks. Traditional scalp retractors are mainly fixed by hanging the tip on the bed sheet. Although this method can fix the scalp to a certain extent, it has the problem of insufficient stability and may become loose over time, thus affecting the safety and convenience of the operation. In addition, the design of the traditional scalp retractor is not convenient for replacing its components. For this reason, a split scalp retractor is provided. Utility Model Content

[0003] The utility model aims at the above-mentioned problems existing in the prior art and provides a split scalp retractor.

The fixed end and the elastic connecting piece, as well as the elastic connecting piece and the scalp hooking end are detachably connected. The fixed end is used to be fixed to a bed sheet, and the scalp hooking end is used to hook the scalp to facilitate surgery. The two ends of the elastic connecting piece are connected to the fixed end and the scalp hooking end, and the elastic connecting piece provides elasticity and deformation length for the scalp hook.

[0005] Preferably, the fixed end includes a base, a limit pin and a top cover, and a plurality of limit pins are arranged side by side on the base. The base passes through the bed sheet through the limit pins and is inserted into the top cover, and the limit pins and the top cover are limited by a latch.

[0006] Preferably, a tightening spring is sleeved on the end of the latch, a first end of the tightening spring is fixedly connected to the latch, and a second end of the tightening spring is fixedly connected to the top cover.

[0007] Preferably, the latch is inserted into the inner side of the top cover, and a gap is provided at the center line of the latch in the axial direction, and a protrusion is integrally connected to the side wall of the end of the latch.

[0008] Preferably, the elastic connecting member comprises an elastic member and spring buckles located at two ends of the elastic member.

[0009] Preferably, the scalp hooking end comprises a curved hook and a connecting rope, and the curved hook and the connecting rope are an integrated structure.

[0010] Preferably, a connecting ring cooperating with a spring buckle is installed at the top end of the top cover.

[0011] Preferably, a connecting ring cooperating with a spring buckle is installed at the bottom end of the connecting rope.

DETAILED DESCRIPTION

[0019] The following is a further detailed description through specific implementation methods:

[0020] like Figures 1 to 3As shown, a split scalp retractor comprises a fixed end 1, an elastic connector 2, and a scalp hooking end 3. The fixed end 1 and the elastic connector 2 and the scalp hooking end 3 are detachably connected. The fixed end 1 is used to be fixed to a bed sheet, and the scalp hooking end 3 is used to hook the scalp for convenient surgery. The two ends of the elastic connector 2 are connected to the fixed end 1 and the scalp hooking end 3. The elastic connector 2 provides elasticity and deformation length for the scalp retractor. The fixed end 1 comprises a base 101, a limit pin 102 and a top cover 103, and a plurality of limit pins 102 and a top cover 103. The needles 102 are arranged side by side on the base 101, and the base 101 passes through the bed sheet through the limiting needles 102 and is inserted into the top cover 103. The limiting needles 102 and the top cover 103 are limited by the plug 104. The limiting needles 102 are provided with limiting holes 108 corresponding to the plug 104. This design can stably fix the scalp retractor on the bed sheet, and it is fixed with the fixed end 1. The fixed position is easy to adjust, and it only needs to be combined with the bed sheet. The bed sheet is an indispensable item in the operation, so it greatly increases the practical convenience and stability.

[0021] Specifically, a tightening spring 105 is sleeved on the end of the latch 104 , a first end of the tightening spring 105 is fixedly connected to the latch 104 , and a second end of the tightening spring 105 is fixedly connected to the top cover 103 .

[0022] Specifically, the latch 104 is inserted into the inner side of the top cover 103 , and a gap 106 is provided at the center line of the latch 104 along the axial direction, and a protrusion 107 is integrally connected to the side wall of the end of the latch 104 .

[0023] Specifically, the elastic connecting member 2 includes an elastic member 201 and spring buckles 202 located at both ends of the elastic member 201, and a connecting ring 4 that cooperates with the spring buckles 202 is installed on the top of the top cover 103;

[0024] The scalp hooking end 3 includes a curved hook 301 and a connecting rope 302 . The curved hook 301 and the connecting rope 302 are an integrated structure. A connecting ring 4 that cooperates with the spring buckle 202 is installed at the bottom end of the connecting rope 302 .

[0025] When in use, hook the hook 301 onto the scalp, and then pull out the latch 104. Due to the elastic force limitation of the gap 106, the latch 104 cannot be completely pulled out, that is, the latch 104 cannot be removed, which is convenient for alignment when fixing again. Then, the base 101 is removed, the drape is folded into wrinkles, and then the limiting needle 102 is passed through the wrinkles and inserted into the inner side of the top cover 103, and then the latch 104 is released, and the base 101 can be fixed. At this time, the fixed end 1 fixes the drape, and the operation can be performed; at the same time, the gap 106 increases the deformation space of the latch 104, so that the protrusion 107 is provided to increase stability while also facilitating the pulling of the latch 104;

[0026] And because both ends of the elastic connecting member 2 are spring buckles 202, the principle of the spring buckle 202 is similar to that of a common key chain, so the principle is not repeated here. The fixed end 1 or the scalp hooking end 3 can be easily removed, and any component can be replaced.

[0027] The above are only embodiments of the utility model. The common sense such as the known specific structures and characteristics in the scheme is not described in detail here. The ordinary technicians in the relevant field are aware of all the common technical knowledge in the technical field to which the utility model belongs before the application date or priority date, can obtain all the existing technologies in the field, and have the ability to apply the conventional experimental means before that date. The ordinary technicians in the relevant field can improve and implement the scheme in combination with their own abilities under the enlightenment given by this application. Some typical known structures or known methods should not become obstacles for the ordinary technicians in the relevant field to implement this application. It should be pointed out that for the technicians in this field, without departing from the structure of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
