Abstract
Description
Technical Field
[0001] The invention discloses a subcutaneous implantation device, belonging to the technical field of medical devices. Background Art
[0002] Subcutaneous implant contraception is one of the safe long-term contraceptive methods. This method has been promoted for many years around the world. It mainly involves implanting a certain dose of subcutaneous implant on the inner side of the user's upper arm. Subcutaneous implants are mainly made of thin and long rods or capsules made of sustained-release materials such as silicone rubber or plastic as carriers. They contain a certain dose of progesterone. After being implanted subcutaneously, they can continuously release low doses of progesterone to achieve the effect of contraception.
[0003] During subcutaneous implantation surgery, it is often necessary to implant multiple implants at a time. During the specific operation, the subcutaneous implant is first unpacked and taken out from a separate package, and then picked up with auxiliary instruments such as tweezers and slowly inserted into the inner cavity of the needle tube, and then pushed in with a push rod. Repeat the operation until several subcutaneous implants are implanted. For subcutaneous implantation surgeries like this traditional implant needle, the medical staff has cumbersome operating steps and low surgical efficiency. In addition, in the interval between the implantation of two implants, the subcutaneous implant comes into contact with the clamping tool and is exposed to the air for a long time, increasing the chance of contamination.

An implant needle 2 is detachably arranged at the front end of the fixed frame 3, and a push rod 5 is arranged at the rear of the fixed frame 3. The push rod 5, the chamber body of the medicine chamber 4 and the implant needle 2 are opposite to each other front and back. After the implant needle 2 pierces the human skin, the medicine in the medicine chamber 4 is pushed into the subcutaneous tissue of the human body by the push rod 5 to complete the implantation of the medicine.
[0027] The structure of the push rod 5 is as follows: Figure 6 As shown, it includes a long core rod 19 and a pusher head 20 concentrically fixed to the rear end of the core rod 19. When performing an implantation operation, after the position of the medicine in the medicine chamber 4 is set, the pusher 5 is pushed in from the rear end of the fixed frame 3, and the core rod 19 is used to gradually push the medicine into the subcutaneous tissue.
[0028] A removable sheath 1 is provided at the front end of the fixing frame 3. When not in use, the sheath 1 can be installed at the front end of the fixing frame 3 to protect the implant needle 2. A plurality of scale lines 6 are also provided on the surface of the needle body of the implant needle 2 so that the doctor can observe the distance of the implant needle 2 when performing the implantation operation.
[0029] like Figures 2~4As shown, the fixing frame 3 includes a rectangular frame body 10, and a fixed seat 13 is arranged at the front end of the frame body 10, so that the frame body 10 is a closed loop. A front push hole 14 is opened in the middle of the fixed seat 13, and the front push hole 14 is arranged along the length direction of the frame body 10 and passes through the front and rear end surfaces of the fixed seat 13; a rear push hole 12 is opened at the rear end of the frame body 10, and the rear push hole 12 is also a through hole passing through the rear edge of the frame body 10, and the axes of the rear push hole 12 and the front push hole 14 are colinear.
[0030] A mounting platform 8 is provided at the front end of the fixing seat 13, through which the sheath 1 is conveniently installed. A front bayonet seat 9 is provided at the top of the fixing seat 13, and a rear bayonet seat 11 is provided on the upper surface of the frame 10, and the bayonet in the front bayonet seat 9 and the bayonet in the rear bayonet seat 11 are arranged opposite to each other in front and back. Arc-shaped handles 7 are also provided on both sides of the fixing seat 13, so that the doctor can clamp the subcutaneous implant device when performing implantation surgery.
[0031] like Figure 5 As shown, the medicine chamber 4 includes a plurality of cartridges 17, which are tubular and extend from front to back, and an implant is arranged in the inner cavity of the cartridge 17. In the present implantation device, two cartridges 17 are provided. The two cartridges 17 are arranged at a right angle, and the centers of the two cartridges 17 are in a common circle. The cartridges 17 may also be provided in other numbers, such as 3 to 6. When the cartridges 17 are provided in other numbers, all the cartridges 17 are arranged at equal angles, and the centers of all the cartridges 17 are in a common circle.
[0032] A clamping shaft 18 is vertically arranged at the front and rear ends of all the cartridge 17 joints, and the front and rear clamping shafts 18 correspond to the clamps in the front clamp seat 9 and the rear clamp seat 11 respectively. By clamping the two clamping shafts 18 in the front clamp seat 9 and the rear clamp seat 11 respectively, the medicine chamber 4 is fixed to the fixed frame 3, and the cartridge 17 rotates in the fixed frame 3.
[0033] A limiting protrusion 16 is also protrudingly provided on the upper part of the clamping shaft 18 at the front end of the cartridge 17, and limiting ribs 15 are respectively provided on both sides of the rear end of the clamping seat 9. After the medicine bin 4 and the fixed frame 3 are completed, the limiting protrusion 16 is located below the limiting rib 15 on one side, and the medicine bin 4 is limited by the limiting rib 15 to prevent the medicine bin from rotating during the implantation operation.
[0034] The specific working process and working principle are as follows:
[0035] Before the implantation operation, end caps are respectively provided at both ends of the medicine bin 4, and the end caps are used to protect the medicine in the medicine bin 4 to avoid contamination. When the implantation operation is performed, the end caps at both ends of the medicine bin 4 are removed, and the two clamping shafts 18 are respectively clamped in the front clamping seat 9 and the rear clamping seat 11 to fix the medicine bin 4 to the fixing frame 3.
[0036] After the medicine bin 4 is loaded into the fixed frame 3, the front and rear ports of one of the medicine cartridges 17 therein are respectively opposite to the front push hole 14 and the rear push hole 12, and at the same time, the limiting protrusion 16 at the front end of the medicine bin 4 is clamped at the limiting rib 15 on one side, and the limiting rib 15 is used to limit the medicine bin 4 to prevent the medicine bin 4 from rotating during the implantation operation. After the medicine cartridge 17 is aligned with the front push hole 14 and the rear push hole 12, the axis of the medicine cartridge 17 and the front push hole 14 and the rear push hole 12 are colinear.
[0037] After the doctor removes the sheath 1, he inserts the implant needle 2 into the human skin and inserts the implant needle 2 to a corresponding distance according to the scale on the surface of the implant needle 2. After the implant needle 2 is sent to a suitable position, the doctor inserts the push rod 5 from the rear end of the fixed frame 3, and the core rod of the push rod 5 passes through the rear push hole 12 and enters the cartridge 17, pushing the implant in the cartridge 17 forward, and the implant passes through the front push hole 14 and enters the implant needle 2, and then is implanted into the human body through the implant needle 2.
[0038] After completing the implantation of the first implant, the doctor takes out the push rod 5, rotates the medicine chamber 4, makes the other medicine cartridge 17 face the front push hole 14 and the rear push hole 12 respectively, and then inserts the push rod 5 again to use the push rod 5 to implant the second implant into the human body.
[0039] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
