Description

Technical Field

[0001] This utility model relates to the field of vascular examination technology, specifically a device suitable for forensic vascular examination. Background Technology

[0002] In vascular surgery, vascular anastomosis is generally performed manually, which requires a very high level of professional skill from the surgeon. In cases of cerebral hemorrhage, the location of the bleeding must be detected first before vascular anastomosis can be performed.

[0003] According to the patent application with publication number CN117618050A, a vascular anastomosis device suitable for vascular surgery is disclosed. During use, the extension strip can guide the blood vessel, making it easier for the blood vessel to be everted and fitted onto the extension strip. The end of the everted part of the blood vessel is pressed down by the elastic pressure strip, and the position of the everted part of the blood vessel corresponding to the end of the extension strip is lifted up, which can reduce the difficulty of vascular anastomosis surgery.

[0004] However, during anastomosis, it is necessary to stop the bleeding of blood vessels first. Hemostasis is inconvenient and the hemostasis effect is poor. At the same time, due to the outflow of blood and the obstruction of blood, it is inconvenient to detect the bleeding location and locate the bleeding location.

[0005] Therefore, we propose a device suitable for forensic vascular examination. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a device suitable for forensic vascular examination, solving the problems of inconvenient hemostasis and inconvenient location of bleeding in existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a device suitable for forensic vascular examination, comprising finger ring sleeve A and finger ring sleeve B positioned opposite each other;

[0008] Fixed rods of opposite positions and matching specifications are fixedly installed on the outer walls of the ring sleeves A and B. Connecting arms A and B of opposite positions are fixedly installed on the rear side of the fixed rods. The rear sides of connecting arms A and B are connected by hinge seats. Clamping arms A and B of opposite positions and matching specifications are respectively mounted on the rear side of the hinge seats. Limiting blocks A and B of opposite positions are fixedly installed on the inner side of the fixed rods. The top surface of the limiting block A has evenly distributed toothed grooves. The bottom surface of the limiting block B has evenly distributed toothed blocks. Clamping blocks A and B of even distribution and opposite positions are fixedly installed on the inner side of the clamping arms A and B. Clamping blocks A and B are made of rubber material.

[0009] A fixed bracket is fixedly installed on the outer wall of the ring sleeve B, with opposite positions. A syringe is mounted on the top surface of the fixed bracket. A connecting head A is mounted on the rear side of the syringe. A rubber tube of the same specification is mounted on the rear side of the connecting head A. A connecting head B of the same specification is mounted on the rear side of the rubber tube. A needle of the same specification is mounted on the connecting head B.

[0010] Preferably, the needle is fitted with a protective sleeve of the appropriate size to protect the needle.

[0011] Preferably, a winding rod is fixedly installed on the right side of the fixing frame, and a limiting plate is fixedly installed at the right end of the winding rod, so that the tube can be wound around the winding rod after injection.

[0012] Preferably, the front side of the fixing frame has a placement slot that matches the size of the protective sleeve, so that the needle and the protective sleeve can be placed into the placement slot for easy storage.

[0013] Preferably, a limiting frame adapted to the specifications of the syringe is fixedly installed on the top surface of the fixing frame, so as to limit and place the syringe.

[0014] Preferably, the rear ends of the clamp arms A and B are curved upwards, which facilitates the use of the hemostat and improves its practicality.

[0015] 1. This device, applicable to forensic vascular examination, features clamp arms, clamping blocks, and limiting blocks. A finger is placed inside a finger ring sleeve, and clamp arms A and B clamp the blood vessel. Clamping blocks A and B further clamp the blood vessel, improving clamping stability and effectiveness. Two sets of hemostatic forceps clamp the left and right sides of the blood vessel for hemostasis. The toothed blocks on limiting block B engage in toothed grooves, freeing the hands and making hemostasis simple, convenient, and effective.

[0016] 2. Simultaneously, by using a syringe, tubing, and needle, after stopping the bleeding in the blood vessel, physiological saline is injected into the blood vessel through the tubing and needle using the syringe to clean the blood vessel, thereby making it easier to clearly observe the bleeding location and facilitate the detection and localization of the bleeding site.

Connecting arms A5 and B6, with corresponding positions, are fixedly installed on the rear sides of the fixed rods 4. The rear sides of connecting arms A5 and B6 are connected by hinge seats 7. Clamping arms A8 and B9, with corresponding positions and matching specifications, are respectively mounted on the rear sides of hinge seats 7. Limiting blocks A10 and B12, with corresponding positions, are fixedly installed on the inner sides of the fixed rods 4. The top surface of limiting block A10 has evenly distributed toothed grooves 11, and the bottom surface of limiting block B12 has evenly distributed toothed blocks 13. Clamping arms A8 and B9... Evenly distributed and relatively opposite clamping blocks A14 and B15 are fixedly installed on the inner sides of clamp arms B8 and B9, respectively. Clamping blocks A14 and B15 are made of rubber material. With the clamp arms, clamping blocks and limiting blocks set up, the fingers are put into the finger ring sleeve, and then the clamp arms A8 and B9 are driven to clamp the blood vessel. Clamping blocks A14 and B15 clamp the blood vessel, improving the stability and effect of clamping. The two sets of hemostatic forceps clamp the left and right sides of the blood vessel to stop bleeding. The toothed block 13 on the limiting block B12 is locked in the toothed groove 11, which can free the hands, making hemostasis simple and convenient and improving the hemostatic effect.

[0025] Example 2:

[0026] like Figure 2-4As shown: A fixing bracket 3 is fixedly installed on the outer wall of the ring sleeve B2, with opposite positions. A syringe 16 is mounted on the top surface of the fixing bracket 3. A connecting head A17 is mounted on the rear side of the syringe 16. A rubber tube 18 of the same specification is mounted on the rear side of the connecting head A17. A connecting head B19 of the same specification is mounted on the rear side of the rubber tube 18. A needle 20 of the same specification is mounted on the connecting head B19. After hemostasis is achieved by setting up the syringe 16, the rubber tube 18 and the needle 20, the syringe 16 injects saline into the blood vessel through the rubber tube 18 and the needle 20 to clean the blood vessel, thereby making it easier to clearly observe the bleeding location and to detect and locate the bleeding location.

[0027] Example 3:

[0028] like Figure 2-3 As shown: A winding rod 22 is fixedly installed on the right side of the fixing frame 3, and a limiting plate 23 is fixedly installed on the right end of the winding rod 22, so that the tube 18 can be wound around the winding rod 22 after the injection is completed.

[0029] The working principle and usage process of this utility model are as follows: When the device is needed, the finger is put into the finger ring sleeve, and then the clamping arms A8 and B9 are driven to clamp the blood vessel. The clamping blocks A14 and B15 clamp the blood vessel, improving the stability and effect of clamping. The two sets of hemostatic forceps clamp the left and right sides of the blood vessel to stop bleeding. The toothed block 13 on the limiting block B12 is locked in the toothed groove 11, which frees the hands. Hemostasis is simple and convenient, and the hemostatic effect is improved. At the same time, after the blood vessel is hemostatic, physiological saline is injected into the blood vessel through the syringe 16, the rubber tube 18 and the needle 20 to clean the blood vessel, so that the bleeding location can be clearly observed and the bleeding location can be detected and located.
