Abstract
The utility model relates to a medical instrument part, in particular to a medical puncture outfit casing, which comprises a casing seat, a sleeve and a hollow casing which are orderly connected, wherein an air valve is arranged on the sleeve, the casing seat is provided with an axial through hole, one side of the casing close to the head is provided with magnets, magnetic sealing plates which are matched with the magnets are arranged in the sleeve, the side close to the sleeve in the casing seat is provided with steps which are matched with the magnetic sealing plates, and the casing seat and the sleeve are sealed with the steps through the magnetic sealing plates. The medical puncture outfit casing has the beneficial effects that 1 the sealing plates are uniformly stressed by adopting magnetic force to seal, and an instrument conveniently and freely goes in and out when puncturing, thereby not being abraded; and 2 a channel is automatically sealed by the magnetic sealing plates after the instrument is taken out from the hollow casing, and the medical puncture outfit casing is excellent in sealing and is durable in use.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments parts, especially a kind of medical thrust device sleeve pipe.
Background technology
Perforator is the main apparatus in the splanchnocoel videoendoscopic surgery, and the quality of its quality directly has influence on what of speed and carbon dioxide use amount of operation process.In laparoscopic surgery; Usually charge into carbon dioxide at intraperitoneal, with the space between increase stomach wall and internal organs, and the telescopic main effect of perforator is exactly to form passage and the close passage that operating theater instruments gets into intracavity; Do not cause carbon dioxide to leak, operation is carried out smoothly from intracavity.In the prior art, the perforator sleeve pipe mainly is to renovate with silica gel sealing medicated cap or spring to control telescopic passage, stops gas leak; And these two kinds of products all have critical defect: silica gel sealing has easy ageing, service life to lack; Be prone to shortcomings such as gas leakage, and spring has been renovated the assembly structure complicacy, spring is yielding; Elastic force is not enough or fracture, unbalance stress and apparatus easy to wear be prone to shortcoming such as gas leakage.Chinese patent CN2553749Y discloses a kind of perforator sleeve pipe, is characterized in being provided with in the body elastic sealing element and is connected overlapping on the seat, and the end face of sealing part is uniformly distributed with the opening and closing seam.Though it is laborsaving that this utility model makes puncture needle or operating theater instruments pass in and out body, do not damage the head of puncture needle and all kinds of surgical instruments, service time one is long, and its sealing property unavoidably can be worse and worse.
Summary of the invention
The medical thrust device sleeve pipe that the technical problem that this utility model will solve is that a kind of good airproof performance is provided, is difficult for the wearing and tearing apparatus.
The technical scheme of this utility model: a kind of medical thrust device sleeve pipe; Comprise the casing seat, sleeve and the hollow sleeve that connect successively, said sleeve is provided with air valve, and casing seat has axially extending bore; Said casing seat is equipped with Magnet near a side of head; Be provided with the magnetic seal sheet that cooperates Magnet in the said sleeve, be provided with the step that cooperates the magnetic seal sheet near sleeve one side in the said casing seat, said casing seat and sleeve are through magnetic seal sheet and step sealing.
Preferably, the both ends of the surface of said magnetic seal sheet middle part has arc-shaped concave.The magnetic seal sheet generally adopts to be inhaled mutually with Magnet but not to go up the soft magnetic materials of magnetic.
The beneficial effect of this utility model is: 1, adopt magnetic seal, diaphragm seal is stressed evenly, and conveniently freely, apparatus does not does not wear and tear during apparatus turnover puncture.2, apparatus is by after taking out in the sleeve pipe, the automatic closed channel of magnetic seal sheet, good airproof performance is durable in use.
Description of drawings
Fig. 1 is the structural representation of this utility model;
Fig. 2 is the working state schematic representation of this utility model;
Fig. 3 is the structural representation of magnetic seal sheet in this utility model.
1. casing seats among the figure, 2. sleeve, 3. hollow sleeve, 4. air valve, 5. Magnet, 6. magnetic seal sheet, 7. step, 8. puncture needle, 9. arc-shaped concave.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is done further explain, but the protection domain of this utility model is not limited to this.
Shown in Fig. 1-3, a kind of medical thrust device sleeve pipe comprises the casing seat 1, sleeve 2 and the hollow sleeve 3 that connect successively; Sleeve 2 is provided with air valve 4; Casing seat 1 has axially extending bore, and casing seat 1 is equipped with Magnet 5 near a side of head, is provided with the magnetic seal sheet 6 that cooperates Magnet 5 in the sleeve 2; Be provided with the step 7 that cooperates magnetic seal sheet 6 near sleeve 2 one sides in the casing seat 1, casing seat 1 passes through magnetic seal sheet 6 and step 7 sealings with sleeve 2.The both ends of the surface middle part of magnetic seal sheet 6 has arc-shaped concave 9.
During this utility model work, after puncture needle 8 inserted the perforator sleeve pipe, syringe needle backed down magnetic seal sheet 6, and this moment, puncture needle 8 self made casing seat 1 and sleeve 2 seal.And after puncture needle 8 was taken out by the perforator sleeve pipe, the suction of Magnet 5 makes magnetic seal sheet 6 auto-closing passages can carry out smoothly thereby perform the operation.
Claims (2)
1. medical thrust device sleeve pipe; Comprise the casing seat, sleeve and the hollow sleeve that connect successively, said sleeve is provided with air valve, and casing seat has axially extending bore; It is characterized in that: said casing seat is equipped with Magnet near a side of head; Be provided with the magnetic seal sheet that cooperates Magnet in the said sleeve, be provided with the step that cooperates the magnetic seal sheet near sleeve one side in the said casing seat, said casing seat and sleeve are through magnetic seal sheet and step sealing.
