Problems solved by technology

The current conventional surgical instruments are mainly orthopedic soft tissue and tumor curettes. Although there are different specifications and models to choose from, they are mainly designed in the shape of a round spoon at the distal end. Left and right, and this type of curette is designed to be suitable for different operation spaces through different sizes and models. Each operation requires 3 to 5 curettes of different specifications; and it is generally necessary to press hard during the operation to improve the curettage efficiency, which may cause damage to normal tissues. crush damage

Embodiment 1

[0050] A pen-shaped debridement device is characterized in that, comprising

[0051] Debridement head 1, described debridement head 1 is hollow, is provided with cavity inside, comprises

[0052] A scraper 11, provided with several, is connected with the debridement head 1 and is located on the outer side of the debridement head 1;

[0053] The adsorption opening 12 is arranged on the debridement head 1 and corresponds to the scraper 11; the adsorption opening 12 communicates with the cavity, and is used to allow the scraped material of the scraper 11 to enter the cavity;

[0054] The grip rod 3 is provided with a cavity 31 inside, and the cavity 31 runs through the grip rod 3;

[0055] The connecting part 2 is connected to the tail of the debridement head 1 at one end, and connected to the holding rod 3 at the other end.

[0056] The scraper 11 is provided with a blade 111, the blade 111 is arc-shaped, and the radian is greater than or equal to 180 degrees; the scraper 11 i...

Embodiment 2

[0070] On the basis of Embodiment 1, the threaded connection between the connecting part 2 and the grip rod 3 and the technical features related to the threaded connection are cancelled;

[0071] The connection part 2 and the holding rod 3 are clamped and fixed, and the holding rod 3 and the connecting part 2 are respectively provided with a locking block 33 and a buckle 28, and the locking block 33 and the buckle 28 are mated and connected. . Through the clamping method, one is to increase the convenience of installation and disassembly. In one operation, multiple debridement heads 1 can be replaced to complete multiple sampling of diseased tissues, which is also more convenient in later maintenance; The problem of tissue getting stuck in the thread makes the connection tighter and reduces tissue residue.

[0072] The clamping block 33 and the buckle 28 are respectively arranged on the outside of the grip bar 3 and the connecting part 2; the clamping block 33 and the buckle ...

Embodiment 3

[0075] On the basis of Embodiment 1 or 2, an additional rotating part is provided;

[0076] A rotating part 6 is provided between the debridement head 1 and the connecting part 2, and the rotating part 6 includes

[0077] The clamping shell 61 is fixedly connected with the connecting part 2;

[0078] The rotating ball center 63 is located in the clamping shell 61 and can rotate freely relative to the clamping shell 61;

[0079] Wherein, the upper end of the debridement head 2 is connected with an extension sleeve 14; the extension sleeve 14 runs through the rotating spherical center 63 and is fixedly connected with the rotating spherical center 63. The connection part 2 is connected, and the cavity for the debridement head 1 communicates with the connection part 2.

[0080] A lubricating layer 62 is provided between the clamping shell 61 and the rotating ball center 63 to ensure lubrication.

[0081] A damping layer is also provided between the clamping shell 61 and the rot...

Abstract

The invention discloses a pen-shaped debridement device. The pen-shaped debridement device is characterized by comprising a debridement head which is hollow, a plurality of scrapers connected with thedebridement head and positioned on the outer side face of the same, an adsorption opening arranged on the debridement head, corresponding to the scrapers, communicated with a containing cavity and used for enabling substances scraped by the scrapers to enter the containing cavity, a holding rod and a connection portion, where the containing cavity is formed inside the debridement head, a cavity is formed inside the holding rod and penetrates the same, and one end of the connection portion is connected with the tail of the debridement head while the other end of the same is connected with theholding rod. The pen-shaped debridement device has the advantages of being simple in structure, portable and stable to operate and having elasticity and steering ability.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pen-shaped debridement device. Background technique [0002] Chronic infection and acute open injury wounds are common types of trauma in orthopedics. Benign soft tissue tumors and other masses without clear boundaries with surrounding tissues are also common types of elective surgery. In the above detection and cleaning of lesion tissue, the purpose of surgery is to remove as much lesion tissue as possible to reduce residual and possible pollutants. The current conventional surgical instruments are mainly orthopedic soft tissue and tumor curettes. Although there are different specifications and models to choose from, they are mainly designed in the shape of a round spoon at the distal end. Left and right, and this type of curette is designed to be suitable for different operation spaces through different sizes and models. Each operation requires 3 to 5 curettes of dif...
