Description

Technical Field

[0001] This utility model relates to the field of puncture device technology, specifically a minimally invasive incision protective sleeve for a puncture device. Background Technology

[0002] A trocar is a passive surgical instrument widely used in clinical practice for puncture procedures such as sampling and drug injection. It is characterized by its convenience, safety, and hygiene, and typically consists of a cannula, needle, and protective cap. The design of the trocar makes puncture procedures more convenient and safer, featuring a sharp needle that can easily pierce the skin and tissue, while the cannula prevents the needle from slipping or shifting, ensuring the stability of the puncture site.

[0003] In existing technologies, when using a trocar, a protective sheath is usually used to protect the incision site to avoid secondary damage to the incision site. Most sheaths usually have a pull cord so that the protective sheath can be pulled out of the incision site after the operation. However, the pull cord may break, and improper operation may also strain the incision site. Therefore, an improved design of the protective sheath for the minimally invasive incision of a trocar has been proposed. Utility Model Content

[0004] The purpose of this invention is to provide a minimally invasive incision protective sleeve for a puncture instrument, in order to solve the problem that most sleeves proposed in the prior art usually have a pull cord so that the protective sleeve can be pulled out from the incision after the operation. However, the pull cord may break, and improper operation may also damage the incision site.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a minimally invasive incision protective sleeve for a puncture device, comprising a conical sleeve, a connecting structure at the top of the conical sleeve, an annular sleeve installed at the bottom of the conical sleeve, a conical air cavity formed inside the conical sleeve, an annular air cavity formed inside the annular sleeve, the conical air cavity communicating with the annular air cavity, an inflation hose connected to the conical air cavity installed on the outside of the conical sleeve, one end of the inflation hose being fixedly connected to a connector, and one end of the connector being provided with an air inflation structure.

[0006] Preferably, the connecting structure includes a conical membrane, which is fixedly connected to the top of the conical sleeve, and an outer retaining ring is installed on the top of the conical membrane.

[0007] Preferably, the air-inflating structure includes an air cylinder with a square cavity inside. An exhaust pipe communicating with the square cavity is installed at one end of the air cylinder, and the exhaust pipe is fixed to a connector.

[0008] Preferably, the air-inflating structure further includes a square plug, which is disposed inside a square cavity and slidably connected to the air cylinder. One end of the square plug is rotatably connected to a threaded rod, one end of which passes through the inside of the square cavity and extends to the outside of the air cylinder. The threaded rod is threadedly connected to the air cylinder, and a handle is installed at one end of the threaded rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This application utilizes a reverse rotation of the handle to connect the threaded rod to the gas cylinder. The threaded rod moves out of the gas cylinder and drives the square plug to slide towards the inside of the gas cylinder, thereby extracting the gas from the conical and annular gas chambers. This causes the conical and annular sleeves to contract, making it easy for personnel to remove the conical and annular sleeves from the cut. This structural design eliminates the need for a rope to remove them, improving the practicality of the device. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1 - Figure 4As shown, this utility model provides a technical solution for a minimally invasive incision protective sleeve for a puncture device, including a conical sleeve 3. The top of the conical sleeve 3 is provided with a connecting structure, which includes a conical membrane 1. The conical membrane 1 is fixedly connected to the top of the conical sleeve 3. An outer retaining ring 2 is installed on the top of the conical membrane 1. An annular sleeve 4 is installed at the bottom of the conical sleeve 3. A conical air cavity 30 is formed inside the conical sleeve 3. An annular air cavity 40 is formed inside the annular sleeve 4. The conical air cavity 30 and the annular air cavity 40 are connected. An inflation hose 5 connected to the conical air cavity 30 is installed on the outside of the conical sleeve 3. A connector 6 is fixedly connected to one end of the inflation hose 5. An air inflation structure is provided at one end of the connector 6.

[0018] The air pumping structure includes an air cylinder 7, which has a square cavity 70 inside. An exhaust pipe 71 communicating with the square cavity 70 is installed at one end of the air cylinder 7. The exhaust pipe 71 is fixed to the connector 6. The air pumping structure also includes a square plug 10, which is disposed inside the square cavity 70 and slidably connected to the air cylinder 7. A threaded rod 9 is rotatably connected to one end of the square plug 10. One end of the threaded rod 9 passes through the inside of the square cavity 70 and extends to the outside of the air cylinder 7. The threaded rod 9 is threadedly connected to the air cylinder 7. A handle 8 is installed at one end of the threaded rod 9.

[0019] Specifically, after making the incision, the conical sleeve 3 and the annular sleeve 4 are inserted into the incision. Then, the forward rotation handle 8 is turned, and the threaded rod 9 is threadedly connected to the air cylinder 7. The threaded rod 9 is screwed into the air cylinder 7, and the square plug 10 is moved by the threaded rod 9. The square plug 10 pushes the gas inside the square cavity 70 through the exhaust pipe 71 and the inflation hose 5 into the conical air cavity 30 and the annular air cavity 40, which opens the conical sleeve 3 and the annular sleeve 4 to form a trumpet shape. Then, the outer retaining ring 2 is flipped over to roll up the conical membrane 1, so that the conical sleeve 3 and the annular sleeve 4 can be installed at the incision.

[0020] As for the flipping of the outer clasp 2 and the conical membrane 1, this is an existing technology in the field and will not be elaborated on here.

[0021] If the conical sleeve 3 and annular sleeve 4 need to be removed from the incision after the surgery, turn the handle 8 in the opposite direction. The threaded rod 9 is threadedly connected to the air cylinder 7. The threaded rod 9 moves out of the air cylinder 7 and drives the square plug 10 to slide into the air cylinder 7. This allows the gas in the conical air chamber 30 and annular air chamber 40 to be extracted, causing the conical sleeve 3 and annular sleeve 4 to contract. Therefore, it is convenient for personnel to remove the conical sleeve 3 and annular sleeve 4 from the incision. This structural design eliminates the need to use a rope to remove them, improving the practicality of the device.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
