Abstract

The utility model relates to a puncture trocar for western medicine internal medicine. An outer cannula is arranged in a holding sleeve. A puncture needle is embedded into the outer cannula in a sleeved mode. The tail, stretching out of the outer cannula, of the puncture needle is provided with a drawing plug. An annular alcohol sponge ring is arranged between the front end of the holding sleeve and the outer cannula. An overflow liquid storage cavity and a fixing ring are sequentially arranged at the tail end of the holding sleeve. The outer wall of the outer cannula is sleeved with the overflow liquid storage cavity, an overflow hole communicated with the overflow liquid storage cavity is formed in the side wall of the outer cannula, and a plurality of sealing rings are arranged between the inner wall, located on the fixing ring, of the outer cannula and the tail end of the outer cannula. The puncture trocar is simple in structure. When operating the puncture trocar, a user holds the holding sleeve with one hand and presses the drawing plug with the other hand to control the puncture depth of the puncture needle. The annular alcohol sponge ring can have the good disinfection function. The puncture trocar is efficient, convenient and quick to operate, and has high practical value.

Description

A kind of doctor trained in Western medicine puncturing trocar for internal medicine
Technical field
This utility model relates to a kind of doctor trained in Western medicine puncturing trocar for internal medicine.
Background technology
In known technical field, current puncture technique is widely used in clinical, as thoracentesis, abdominal paracentesis, joint puncture etc.Existing canula puncture needle is made up of nook closing member and needle guard, in needle guard, is cavity, and nook closing member and needle guard front end are scalene cone, and nook closing member diameter is consistent with needle guard cavity internal diameter, and nook closing member is contained in needle guard through needle guard internal cavity.While using puncture, to puncture needle slowly being inserted after point of puncture sterilization, local anaesthesia, in the time that opposing sense reduces, show to thrust target cavity.Now maintain chamber pressure, water conservancy diversion can be extracted puncture needle after going out certain quantity of fluid, and part compresses, and makes puncturing hole closure.
The shortcoming of common puncture needle has: puncture needle pin hole in use easily occurs and stops up, and water conservancy diversion liquid cannot be derived, and need to repeat inserting needle, and the potential danger that makes to perform the operation increases; In piercing process, puncture needle is difficult for fixing, easily run-bake-needle fault; When nook closing member is extracted out, hydrops easily erupts, and operates wayward; After nook closing member is extracted out, outside air enters operation cavity along needle guard, and negative pressure disappears in cavity, and easily forming pneumothorax etc. affects the phenomenon of patient's life.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, a kind of superinfection, easy to operate doctor trained in Western medicine puncturing trocar for internal medicine avoided is provided.
This utility model solves the technical scheme that its technical problem adopts: a kind of doctor trained in Western medicine puncturing trocar for internal medicine, there is gripping sleeve, in described gripping sleeve, be provided with trocar sheath, being nested with spinosity at described trocar sheath threads a needle, the outside that the afterbody that described thorn is threaded a needle stretches out in trocar sheath is provided with pull plug, between the front end of described gripping sleeve and trocar sheath, be provided with annular alcohol sponge circle, tail end at described gripping sleeve is provided with overflowing liquid storage chamber and retainer ring successively, described overflowing liquid storage chamber is set in the outer wall of trocar sheath, and on the sidewall of described trocar sheath, be provided with the spout hole being connected with overflowing liquid storage chamber, inwall at the trocar sheath at retainer ring place is provided with multiple sealing rings between the tail end of trocar sheath.
Further, as a kind of concrete embodiment, the quantity of sealing ring described in this utility model is 3.
Further, as a kind of concrete embodiment, this utility model is coated with anti-slip rubber circle in the outside of described gripping sleeve.
The beneficial effects of the utility model are: this utility model is simple in structure, in operation, one holds gripping sleeve, another hands is pressed pull plug, control the penetration depth that thorn is threaded a needle, annular alcohol sponge circle can play good disinfective action simultaneously, and it is efficiently convenient to operate, and has practical value.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure: 1. grip sleeve, 2. trocar sheath, 21. spout holes, 3. thorn is threaded a needle, 4. annular alcohol sponge circle, 5. overflowing liquid storage chamber, 6. retainer ring, 7. pull plug, 8. sealing ring, 9. anti-slip rubber circle.
The specific embodiment
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with this utility model.
The preferred embodiment of a kind of doctor trained in Western medicine puncturing trocar for internal medicine of this utility model as shown in Figure 1, there is the sleeve 1 of gripping, in described gripping sleeve 1, be provided with trocar sheath 2, be nested with spinosity at described trocar sheath 2 and thread a needle 3, the described thorn outside that 3 afterbody stretches out in trocar sheath 2 of threading a needle is provided with pull plug 7, between the front end of described gripping sleeve 1 and trocar sheath 2, be provided with annular alcohol sponge circle 4, be provided with successively overflowing liquid storage chamber 5 and retainer ring 6 at the tail end of described gripping sleeve 1, described overflowing liquid storage chamber 5 is set in the outer wall of trocar sheath 2, and on the sidewall of described trocar sheath 2, be provided with the spout hole 21 being connected with overflowing liquid storage chamber 5, at the inwall of the trocar sheath 2 at retainer ring 6 places to being provided with multiple sealing rings 8 between the tail end of trocar sheath 2.
The quantity of described sealing ring 8 is 3.
Be coated with anti-slip rubber circle 9 in the outside of described gripping sleeve 1.
This utility model is simple in structure, and in operation, one holds gripping sleeve, and another hands is pressed pull plug, controls the penetration depth that thorn is threaded a needle, and annular alcohol sponge circle can play good disinfective action simultaneously, and it is efficiently convenient to operate, and has practical value.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to claim scope.
