Abstract
This utility model discloses a kind of teeth engaged type catheter sheath, comprise convergent divergent channel, the sheath base of the sheath pipe be enclosed within convergent divergent channel, connecting utricle pipe, the diaphragm seal being arranged on sheath base upper end and lid, and connect the expansion base of lid, the inwall of described lid is provided with the inside groove that a circle is made up of buckle teeth outwardly, described inside groove is arranged with a pair breach; The outer wall that the lower end of described expansion base is connected with described lid is arranged with a pair convex tooth outwardly, the shape of described convex tooth and the mating shapes of described breach, and the size of convex tooth is slightly smaller than the size of described breach.This utility model is by the mode of breach and convex tooth rotary clamping, and sheath pipe is closely linked together with expanding to manage, and its structure is simple, easy to operate, namely facilitate the carrying out of intervene operation, alleviate again the misery of patient, use when it is specially adapted to cardio-vascular interventional therapeutic.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of teeth engaged type catheter sheath.
Background technology
Catheter sheath is that one is used to percutaneous puncture and inserts vascular system, imports angiographic catheter, guiding catheter, sacculus dilating catheter or support and carries out the medical device product of insertion type invasive treatment.In use, first with percutaneous puncture intubation procedure, seal wire is inserted Ink vessel transfusing.Be enclosed within seal wire by catheter sheath again, catheter sheath is inserted into Ink vessel transfusing along seal wire.Extract seal wire and convergent divergent channel subsequently, only sheath pipe is stayed Ink vessel transfusing, carry out the passage of endovascular procedures as one.
Sheath pipe and convergent divergent channel are all fixed together by hickey by current catheter sheath on the market mostly, but this kind of connected mode makes catheter sheath operation too loaded down with trivial details, is not easy to medical worker's operation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of teeth engaged type catheter sheath, and its structure is simple, easy to operate, is convenient to medical worker and uses.
For solving technical problem of the present utility model, this utility model discloses a kind of teeth engaged type catheter sheath, comprise convergent divergent channel, the sheath base of the sheath pipe be enclosed within convergent divergent channel, connecting utricle pipe, the diaphragm seal being arranged on sheath base upper end and lid, and connect the expansion base of lid, the inwall of described lid is provided with the inside groove that a circle is made up of buckle teeth outwardly, described inside groove is arranged with a pair breach; The outer wall that the lower end of described expansion base is connected with described lid is arranged with a pair convex tooth outwardly, the shape of described convex tooth and the mating shapes of described breach, and the size of convex tooth is slightly smaller than the size of described breach.
Wherein, described teeth engaged type catheter sheath also comprises rubber washer, is placed on the inside groove of described sheath base upper end lid.
Wherein, described teeth engaged type catheter sheath also comprises the anti-broken pipe be enclosed within sheath pipe, and it connects the lower end of described sheath base.
Compared with prior art, this utility model has following beneficial effect: this utility model is by the mode of breach and convex tooth rotary clamping, sheath pipe is managed with expansion closely link together, its structure is simple, easy to operate, namely facilitate the carrying out of intervene operation, alleviate again the misery of patient, use when it is specially adapted to cardio-vascular interventional therapeutic.

Fig. 2 be teeth engaged type catheter sheath of the present utility model the top view of sheath base;
Fig. 3 is the top view of the expansion base of teeth engaged type catheter sheath of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, teeth engaged type catheter sheath of the present utility model, comprise convergent divergent channel 1, the sheath base 4 of the sheath pipe 2 be enclosed within convergent divergent channel 1, connecting utricle pipe 2, the diaphragm seal 5 being arranged on sheath base 4 upper end and lid 6, and connect the expansion base 7 of lid 6, the inwall of described lid 6 is provided with the inside groove 61 that a circle is made up of buckle teeth outwardly, described inside groove 61 is arranged with a pair breach 62; The outer wall that the lower end of described expansion base 7 is connected with described lid 6 is arranged with a pair convex tooth 71 outwardly, the described shape of convex tooth 71 and the mating shapes of described breach 62, and the size of convex tooth 71 is slightly smaller than the size of described breach 62.
In use, will two convex teeth 71 of expansion base 7 lower end, aim at and be inserted in the breach 62 of sheath base 4 upper end lid 6, when the anglec of rotation be greater than 0 ° and be less than 180 ° scope in time, sheath pipe 2 with expand pipe 1 and closely link together.When the anglec of rotation be 0 ° or 180 ° time, sheath pipe 2 with expand pipe 1 and unclamp.
In addition, described teeth engaged type catheter sheath also comprises rubber washer, is placed on the inside groove 61 of described sheath base 4 upper end lid 6, loosens with the connection of convergent divergent channel 1 to prevent sheath pipe 2.
Further, for preventing sheath pipe from fractureing, the teeth engaged type catheter sheath of the present embodiment also comprises the anti-broken pipe 3 be enclosed within sheath pipe 2, and it connects the lower end of described sheath base 4.
In sum, this utility model, by the mode of breach and convex tooth rotary clamping, makes sheath pipe closely link together with expanding to manage, its structure is simple, easy to operate, namely facilitates the carrying out of intervene operation, alleviate again the misery of patient, use when it is specially adapted to cardio-vascular interventional therapeutic.
More than lift preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; be understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc.; all should be included within protection domain of the present utility model; the interest field that this utility model is advocated should be as the criterion described in utility model application scope, but not is only limitted to above-described embodiment.
