[0002] During craniotomy, the commonly used scalp clamp is a surgical instrument specially designed to clamp the scalp and block blood vessels. This scalp clamp is usually made of plastic and is hard and brittle. It is about 1.5 cm long and curled into a cylinder with one side opening in a crenel-like shape. During the operation, the doctor will use a special scalp clamp to open the scalp clamp, and then open it to bite the entire layer of scalp. This can effectively clamp and fix the scalp, while blocking small blood vessels and reducing bleeding.

[0003] Currently, when doctors need to use scalp clips during surgery, nurses need to hand them to the doctors one by one. Since scalp clips are small in size, medical staff wear gloves when grabbing them. It is difficult to grasp the number of scalp clips, which may result in grabbing multiple scalp clips at a time. In this case, they need to pick up a single one and hand it to the doctor. The transfer efficiency of scalp clips is low, which affects the timely hemostasis of the scalp. In addition, when grabbing multiple scalp clips at the same time, it is easy for the scalp clips to fall and be contaminated, and it is not convenient to count the number of scalp clips later.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a fixing device used in conjunction with a scalp clip, comprising: a bottom plate 1 and a fixed shaft 3, a toothed disc 2 is rotatably arranged at the top center of the bottom plate 1, a fixed shaft 3 is fixed at the top center of the toothed disc 2, a fixed cover 4 is fixed at the top of the fixed shaft 3, a spiral guide groove 6 is fixed at the bottom of the fixed cover 4, a slider is slidably arranged inside the spiral guide groove 6, a pressure rod 7 is arranged at the bottom of the slider, a T-shaped groove is provided at the bottom of the spiral guide groove 6, the slider is a T-shaped slider, the bottom of the slider and the top of the pressure rod 7 are hinged, the top of the pressure rod 7 can be turned by hinge as the spiral guide groove 6 rotates, and the pressure rod 7 itself moves up or down under the guidance of the guide hole 19;

[0022] A pressing plate 8 is provided at the bottom of the pressing rod 7, and a bottom protective shell 14 is provided at the top of the bottom plate 1 outside the toothed disc 2. The bottom protective shell 14 is made of transparent plastic material, which is convenient for observing the movement of the scalp clip. There is enough gap between the bottom of the scalp clip placement shell 11 and the toothed disc 2, so that after the pressing plate 8 descends to push out the last scalp clip in the scalp clip placement shell 11, the handle 5 is continued to be turned, and the pressing plate 8 can continue to descend without contacting the toothed disc 2, so as to ensure that the last scalp clip falling on the bottom plate 1 can be guided out to the material trough 18 by the continued rotation of the toothed disc 2.

[0023] A scalp clip placement shell 11 is provided on one side of the bottom protective shell 14, and the scalp clip placement shell 11 is located below the pressure plate 8. An elastic bottom film 13 is provided on one side of the bottom of the scalp clip placement shell 11, and the bottom of the elastic bottom film 13 is located above the toothed disc 2 to prevent affecting the rotation of the toothed disc 2.

[0024] The outer wall of the toothed disc 2 is provided with teeth, and there are six teeth. The six teeth are evenly arranged circumferentially below the toothed disc 2. The number of teeth can be adjusted as needed. When a large number of scalp clips are required for surgery, the number of teeth of the toothed disc 2 can be increased, but the gap between the teeth must be larger than the size of the scalp clip to avoid the problem that the scalp clip cannot fall between the teeth alone.

[0025] A snap-on housing 9 is provided on one side of the top of the bottom protective housing 14. The snap-on housing 9 is U-shaped, and a snap-on slot 10 is provided on both sides of the middle of the snap-on housing 9. A snap-on pin 12 is provided on both sides of the outer wall of the scalp clip placement housing 11. The snap-on slot 10 cooperates with the snap-on pin 12 to fix the scalp clip placement housing 11. The scalp clip placement housing 11 is pushed into the snap-on housing 9, and the scalp clip placement housing 11 is fixed by the cooperation of the snap-on pin 12 and the snap-on slot 10, and the abutment of the snap-on housing 9 and the scalp clip placement housing 11.

[0026] A guide plate 16 is provided at the top of the clamping housing 9, a guide hole 19 is provided in the guide plate 16 outside the pressure rod 7, a through hole is provided in the center of the guide plate 16 outside the fixed shaft 3, and an upper protective cover 17 is provided at the top of the guide plate 16 outside the spiral guide groove 6. The spiral guide groove 6 rotates together, and at this time, the top of the pressure rod 7 moves downward under the pressure of the spiral guide groove 6, and through the guidance of the guide hole 19, the pressure plate 8 is driven to move vertically downward.

[0027] A handle 5 is provided at the center of the top of the fixed cover 4. Turning the handle 5 drives the fixed shaft 3, the fixed cover 4, the toothed disc 2 and the spiral guide groove 6 to rotate together. A support rod is provided between the bottom of the fixed cover 4 and the top of the spiral guide groove 6 to improve the installation stability of the spiral guide groove 6.

[0028] One side of the bottom protective shell 14 is located outside the scalp clip placement shell 11 and is provided with a placement shell retrieval groove 15 to facilitate the installation and removal of the scalp clip placement shell 11 and to facilitate timely placement of the scalp clip in the scalp clip placement shell 11. One side of the bottom protective shell 14 is provided with a material extraction groove 18 to remove the scalp clip between the teeth of the toothed disc 2. The material extraction groove 18 is as close as possible to one side of the scalp clip placement shell 11. When the scalp clip is pressed out, it can be immediately guided out by the toothed disc 2.

[0029] When the spiral guide groove 6 rotates 60 degrees, the descending stroke of the pressure rod 7 is the same as the height of the scalp clip. When there are 6 teeth, the pitch of the spiral guide groove 6 is the same as the height of six scalp clips. When the spiral guide groove 6 rotates 60 degrees, the pressure rod 7 immediately descends to the height of a scalp clip, making it easier for the pressure rod 7 and the pressure plate 8 to press out the scalp clip smoothly.

[0030] The scalp clip placement shell 11 is used to place the scalp clip, and the scalp clip is placed in a single layer from top to bottom inside the scalp clip placement shell 11, and the elastic bottom sheet 13 is arranged obliquely, and the elastic bottom sheet 13 is used to limit the scalp clip. The elastic bottom sheet 13 can prevent the scalp clip from falling due to gravity.

[0031] When the scalp clip fixing device is in use, the handle 5 is turned so that the top of the pressure rod 7 is located at the bottom of the spiral guide groove 6, the scalp clip is inserted from the top of the scalp clip placement shell 11, and then the scalp clip placement shell 11 is pushed into the snap-on shell 9. The scalp clip placement shell 11 is fixed by the cooperation of the bayonet pin 12 and the slot 10, and the abutment of the snap-on shell 9 and the scalp clip placement shell 11. At this time, the pressure rod 7 and the pressure plate 8 are located directly above the scalp clip placement shell 11. When the scalp clip needs to be taken, the handle 5 is turned counterclockwise to drive the fixing shaft 3, the fixing cover 4, the toothed disc 2 and the spiral guide groove 6 to rotate together. At this time, the top of the pressure rod 7 will move downward under the pressure of the spiral guide groove 6, and the pressure plate 8 will be driven to move vertically downward through the guidance of the guide hole 19. The pressing plate 8 squeezes the scalp clip, and the scalp clip at the bottom squeezes the elastic bottom film 13, so that the elastic bottom film 13 opens until the scalp clip at the bottom falls onto the bottom plate 1. At this time, the scalp clip is located between the teeth of the toothed disc 2. It continues to rotate, so that the scalp clip on the bottom plate 1 moves to one side of the material taking slot 18 under the drive of the teeth of the toothed disc 2 until the scalp clip is in the material taking slot 18. At this time, the material is taken. Since there is only one scalp clip between the teeth, it will not cause the problem of grabbing multiple scalp clips at one time. In this way, the handle 5 is continued to be rotated to export the scalp clips on the bottom plate 1 separately in turn, which is convenient for medical personnel to grab one scalp clip at a time, improve the transmission efficiency of the scalp clips, avoid pollution caused by the falling of excess scalp clips, and facilitate the subsequent counting of the number of scalp clips.

[0032] Furthermore, when the scalp clip needs to be re-placed in the scalp clip placement shell 11, the handle 5 is rotated clockwise to make the pressure rod 7 rise under the drive of the spiral guide groove 6 until the pressure rod 7 is separated from the scalp clip placement shell 11, and then the scalp clip placement shell 11 is removed, and the scalp clips are placed in turn and the above steps are repeated.

[0033] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
