This puncture sheath base pin of peritoneoscope interchangeability is good, has enlarged application range.
Description
Technical field
This utility model relates to a kind of laparoscopically puncture sheath bobbin, belongs to medical instruments field.
Background technology
Existing one laparoscopically puncture sheath bobbin, comprise trocar sheath and inner sleeve, inner sleeve is placed in trocar sheath, and trocar sheath is made up of needle body part and handle portion.One end of above-mentioned laparoscopically puncture sheath bobbin is provided with endoscopic port.This entrance difficulty matches with the interface of the hysteroscope, ureteroscope, cystoscope etc. of existing all models, and therefore interchangeability is poor, and the scope of application is restricted.The interface of the hysteroscope, ureteroscope, cystoscope etc. of existing all models, all adopts the buckle structure matched with existing lock nut.
Utility model content
The technical problems to be solved in the utility model is to provide the good laparoscopically puncture sheath bobbin of a kind of interchangeability, expands the scope of application.
In order to solve the problems of the technologies described above, a kind of laparoscopically puncture sheath bobbin of this utility model, containing trocar sheath, inner sleeve, lock nut and snap close; Inner sleeve is placed in trocar sheath, and lock nut is arranged on one end of trocar sheath, and snap close is arranged on one end of inner sleeve, and the other end of inner sleeve is the needle-based structure of entry needle, and snap close can on fastening lock nut, or snap close can be separated with lock nut.
Described snap close is arranged on snap close seat, and the central authorities of this snap close seat are provided with through hole, and this snap close seat is conical structure or ellipsoidal configuration.
Described snap close and snap close seat are overall structure.
The internal diameter of described trocar sheath is 2.9-6.7 millimeter, the wall thickness of trocar sheath is 0.2 millimeter; The external diameter of described inner sleeve is 2.7-6.5 millimeter, and internal diameter is 1-5.5 millimeter.
The length of the needle-based structure of the entry needle of the described inner sleeve other end is 15 millimeters.
The length of described snap close seat is 38 millimeters, and the internal diameter of the through hole that its central authorities are provided with is 3.5 millimeters, and the outside diameter of the snap close seat of described conical structure is 12.2 millimeters, end diameter is 5.8 millimeters; Or the major axis of the snap close seat of described oval structure be 7.8 millimeters, minor axis is 5.8 millimeters.
The hatch frame of the through hole that described snap close seat central authorities are provided with is female cone body structure.
In above-mentioned laparoscopically puncture sheath bobbin, because lock nut is arranged on one end of trocar sheath, this lock nut can match with the snap close of the hysteroscope, ureteroscope, cystoscope etc. of existing all models, and therefore interchangeability is good, expands the scope of application.

Fig. 2 is the syndeton schematic diagram of outer tube and lock nut.
Fig. 3 is the syndeton schematic diagram of interior pipe and snap close.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, a kind of laparoscopically puncture sheath bobbin, containing trocar sheath 3, inner sleeve 2, lock nut 4 and snap close 5.Inner sleeve 2 is placed in trocar sheath 3, and lock nut 4 is arranged on one end of trocar sheath 3, and snap close 5 is arranged on one end of inner sleeve 2, and the other end of inner sleeve 2 is the needle-based structure 1 of entry needle, and snap close 5 can on fastening lock nut 4, or snap close 5 can be separated with lock nut 4.
Described snap close 5 is arranged on snap close seat 6, and the central authorities of this snap close seat 6 are provided with through hole 7, and this snap close seat 6 is conical structure or ellipsoidal configuration.
Described snap close 5 is overall structure with snap close seat 6.
The internal diameter of described trocar sheath 3 is 2.9-6.7 millimeter, the wall thickness of trocar sheath 3 is 0.2 millimeter; The external diameter of described inner sleeve 2 is 2.7-6.5 millimeter, and internal diameter is 1-5.5 millimeter.
The length of the needle-based structure of the entry needle of described inner sleeve 2 other end is 15 millimeters.
The length of described snap close seat 6 is 38 millimeters, and the internal diameter of the through hole 7 that its central authorities are provided with is 3.5 millimeters, and the outside diameter of the snap close seat 6 of described conical structure is 12.2 millimeters, end diameter is 5.8 millimeters; Or the major axis of the snap close seat 6 of described oval structure be 7.8 millimeters, minor axis is 5.8 millimeters.
The hatch frame of the through hole 7 that described snap close seat 6 central authorities are provided with is female cone body structure 8.
In above-mentioned laparoscopically puncture sheath bobbin, because lock nut 4 is arranged on one end of trocar sheath 3, this lock nut 4 can match with the snap close of the hysteroscope, ureteroscope, cystoscope etc. of existing all models, and therefore interchangeability is good, expands the scope of application.
