Abstract
The utility model relates to a medical appliance, and in particular relates to a novel medical trocur. The novel medical trocur comprises a front base and a rear base which are fixedly connected with each other and a cannula which is arranged at the front end of the front base, wherein an air valve is arranged below one side of the front base, which is close to the cannula, a guide tube is arranged at the rear end of the rear base, a channel which is matched with the guide tube is arranged in the rear base, the front edge port of the channel is arranged into a seal port, a seal steel ball which is matched with the seal port is arranged in one side of the cavity of the front base, which is close to the seal port, and a magnet which is matched with the seal steel ball is arranged in the rear base. The hollow seal steel ball of the novel medical trocur can easily and freely roll in the specified channel, thereby easily leaving the channel when the trocur or a surgical instrument extends into the channel, so that the surgical instrument is put in; or when the trocur or a surgical instrument is removed from the channel, the seal steel ball is easily moved to the channel to quickly seal the channel, and simultaneously, the novel medical trocur is difficult to abrade and more durable.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of new medical perforator.
Background technology
Perforator is a medical equipment indispensable in the Minimally Invasive Surgery, and whether the quality of its quality directly has influence on what and the surgical environments of speed and carbon dioxide use amount of operation process desirable.In Minimally Invasive Surgery; Usually charge into carbon dioxide at intraperitoneal; To increase the space between stomach wall and internal organs; And the main effect of perforator be exactly operating theater instruments can be random during into and out of intracavity the open and close passage, and in the whole surgery operating process, do not cause carbon dioxide to leak, operation is carried out smoothly.In the prior art; Perforator mainly is to renovate with silica gel sealing medicated cap or spring to control telescopic passage, stop gas leak, and these two kinds of products all has critical defect: silica gel sealing has shortcomings such as easy ageing, short, easy gas leakage in service life; And spring has been renovated the assembly structure complicacy; Spring is yielding, and elastic force is not enough or fracture, unbalance stress and apparatus easy to wear be prone to shortcoming such as gas leakage.The perforator that the clear magnetic sheet sealing of Crinis Carbonisatus was arranged afterwards; The problem that all seal channels of perforator exist before almost solving; Through clinical practice for many years; Some problems of magnetic sheet sealing perforator are coming out gradually also, is difficult to get into or the like such as hook gauze, 0 ° mirror, and market needs a kind of perforator that can solve above-mentioned defect especially.
Summary of the invention
This utility model is in order to solve defective and the deficiency that above-mentioned prior art exists, provide a kind of simple in structure, operation technique convenient, good airproof performance, the new medical perforator of good, the long service life of anti-wear performance simultaneously.
The technical scheme of this utility model: a kind of new medical perforator; The sleeve pipe of the preceding pedestal that comprises fixed connection pedestal front end with the back pedestal and before being arranged on; Pedestal is provided with air valve near sleeve pipe one side-lower before said; The rear end of said back pedestal is provided with skirt, and the passage that cooperates skirt is set in the back pedestal, and the front side bead of said passage is set to seal; The firm ball of sealing of fitted seal mouth is set near seal one side in the cavity of pedestal before said, the Magnet of fitted seal steel ball is set in the pedestal of said back.
Preferably, said Magnet is arranged on the passage below, and a utmost point of Magnet is towards the seal of passage front side bead.
Preferably, the firm ball of said sealing is that stainless steel material is made into hollow-core construction.
The sealed steel ball of this utility model hollow core can be easily in the passage of regulation arbitrarily rolling, make that sealed steel ball is easy to leave passage when puncture needle or operating theater instruments put in passage, so that let the operating theater instruments entering; Or puncture needle or operating theater instruments when leaving passage sealed steel ball be easy to move into passage so that closed channel fast.In addition sealed steel ball open with closed process in also can rotate, so its sealing surface is uncertain, it is more durable that this just makes that this device is difficult to wearing and tearing.
Description of drawings
Fig. 1 is a kind of structural representation of this utility model puncture state;
Fig. 2 is a kind of structural representation of this utility model sealing state.
Pedestals before 1. among the figure, 2. back pedestal, 3. skirt, 4. sleeve pipe, 5. puncture needle, 6. cavity, 7. passage, 8. air valve, 9. Magnet, 10. sealed steel ball, 11. seals.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is done further detailed explanation, but be not restriction this utility model protection domain.
As depicted in figs. 1 and 2; A kind of new medical perforator, the sleeve pipe 4 of the preceding pedestal 1 that comprises fixed connection pedestal 1 front end with back pedestal 2 and before being arranged on, preceding pedestal 1 is provided with air valve 8 near sleeve pipe 4 one side-lowers; The rear end of back pedestal 2 is provided with skirt 3; The passage 7 that cooperates skirt 3 is set in the back pedestal 2, and the front side bead of passage 7 is set to seal 11, the interior firm ball 10 of sealing that fitted seal mouth 11 is set near seal 11 1 sides of the cavity of preceding pedestal 1; Seal firm ball 10 and be made into hollow-core construction for stainless steel material; Seal firm ball 10 and adopt stainless steel materials to be made into hollow-core construction, reduce the influence of himself action of gravity, reach the purpose of opening fast with closed channel; The Magnet 9 of fitted seal steel ball 10 is set in the back pedestal 2.Magnet 9 is arranged on passage 7 belows, and a utmost point of Magnet 9 makes the magnetic field at seal 11 places the strongest towards the seal 11 of passage 7 front side beads, makes the firm ball 10 of sealing maximum with the contact pressure between the seal 11, the raising sealing effectiveness.
During use, open the air valve 8 below the pedestal 1 before being arranged on, make the cavity 6 of the full preceding pedestal 1 of carbon dioxide, puncture needle 5 or other operating theater instruments stretch in passage 7, push sealed steel ball 10 open and get into sleeve pipes 4, puncture or operation technique again.After puncture or operation technique finish, when puncture needle 5 or other operating theater instruments are left passage 7,, thereby reach the purpose of quick closed channel because magneticaction sealed steel ball 10 is easy to move into the seal 11 of passage.
