In the present embodiment, as shown in Figure 3 and Figure 4, have on the outer wall of the close disk body 42 of locking member 10 and be oppositely arranged
Two buckle ears 14, catching groove 141 is offered on each buckle ear 14, the side towards locking member 10 of disk body 42 is equipped with and two buttons
Slot 141 corresponds two pins 43 of cooperation.Connection type assembly between locking member and anticreep casing is simple, reduces assembly
The labor intensity of personnel.
In the present embodiment, locking member 10 is locking sleeve, the contact area bigger between locking sleeve and sheath, locking
It is more solid and reliable.
In the present embodiment, as shown in figure 5, handle 20 has the first protrusion 21 outwardly protruded, the outer wall of locking sleeve
Upper to have the second protrusion 12 outwardly protruded, the first protrusion 21 and the second protrusion 12 are connect with connector 30.The setting of protrusion
It is convenient to be connect with connector.
In the present embodiment, as shown in Fig. 1, Fig. 5 and Fig. 6, connector 30 includes two first rotating shafts 31 disposed in parallel
With the link block 32 of the middle section of two first rotating shafts 31 of connection, the first protrusion 21 and the second protrusion 12 are equipped with and are oppositely arranged
Two, first protrusion 21 has the first mounting hole, another first protrusion 21 has the first card slot, the first mounting hole and
The both ends of first card slot and a first rotating shaft 31, which correspond, to be coordinated, and second protrusion 12 has the second mounting hole, another
There is the second card slot, the second mounting hole and the second card slot and the both ends of another first rotating shaft 31 to correspond for a second protrusion 12
Cooperation.When installation connecting element is with handle and locking member, after handle 20 is turned to suitable position, it is only necessary to by connector 30
One end of two first rotating shafts 31 is inserted into also cross the card slot on corresponding locking member 10 and handle 20 in mounting hole, at this time
The other end of two first rotating shafts 31 also is located in corresponding card slot.Above-mentioned installation process does not use pin, utilizes axial aperture structure
Mutual movement cooperation, simple installation can be achieved.
In the present embodiment, connector 30 further includes the taper 33 being set in first rotating shaft 31, taper 33
It is connect with link block 32 and between two the second protrusions 12, the outer diameter of taper 33 is along the installation side of connector 30
To reduction.The size of the outer diameter big end of one taper 33 is more than the size of the first card slot, another taper 33 it is outer
The size of diameter big end is more than the size of the second card slot, and after connector 30 is installed, the outer diameter big end of a taper 33 can support
It leans against on the first protrusion 21 of the rear side of the installation direction along connector 30, the outer diameter big end of another taper 33 can be against
On the second protrusion 12 of the rear side of the installation direction along connector 30, connector can be prevented to skid off in this way, by connector jail
Admittedly be mounted on locking member and handle on.
In the present embodiment, there is the third protrusion 13 outwardly protruded, third protrusion 13 and hand on the outer wall of locking sleeve
One end of handle 20 connects.The setting of protrusion is convenient to be connect with handle.
In the present embodiment, there is the protrusion 22 outwardly protruded, protrusion 22 to be equipped with second at the middle part of one end of handle 20
Shaft 23, third protrusion 13 are equipped with two be oppositely arranged, and each third protrusion 13 has one end of the second shaft 23 of installation
Third card slot.When handle and locking member are installed, the both ends of the second shaft 23 on the front end of handle 20 are directly caught in locking member
On 10 in corresponding third card slot, above-mentioned installation process does not use yet, and can realize that mutual movement coordinates using axial trough structure, peace
Dress is easy.
The installation process of fixing device is illustrated with reference to Fig. 5 to Fig. 7：
As shown in figure 5, the both ends of the second shaft 23 on the front end of handle 20 are caught in corresponding third on locking member 10
In card slot, after handle 20 turns to suitable position, as shown in fig. 6, one end of two first rotating shafts 31 of connector 30 is same
When card slot on corresponding locking member 10 and handle 20 be inserted into mounting hole, the other end of two first rotating shafts 31 at this time
It also is located in corresponding card slot；As shown in fig. 7, then sliding into the pin on anticreep casing 40 in catching groove, fixing device is completed
Installation.
The course of work on sheath card is applied to illustrate fixing device below：
Sheath is passed through to the tail end that sheath is slided in the locking sleeve of fixing device and by fixing device, pulling handle will consolidate
Determine device and sheath card 50 is locked；In operative process, mini-incision is carried out in patient abdomen, fixing device will be carried
The leading portion of sheath card 50 be inserted into the abdominal cavity of patient by notch, behind the position for reaching needs, one holds steady sheath card 50, separately
One hand pulls handle, and locking buckle assembly and fixing device are unclamped, and sliding fixing device is until anticreep casing clamp is created cutting in a subtle way
Mouthful, the hangnail body on anticreep casing can prevent sheath Kathon CG dynamic or abjection stomach wall；Pulling handle keeps fixing device and sheath clamping lock tight, from
And sheath fixing is made to be scheduled on stomach wall, ensure being smoothed out for operation, as shown in Figure 8.
As interchangeable embodiment, the distance between 2 points of AC<The distance between 2 points of BC, locking assembly are in pine
When open state, 3 points of A, B and C is linked to be triangle, applies the active force far from connector direction on operating side, when A, B and C connect
In alignment, locking assembly is in dead-centre position at this time and the distance between A and B become smaller；Active force is continued to, has been crossed dead
Locking is realized in point position, and the distance between A and B when the distance between A and B are in releasing orientation than locking assembly at this time are small.
Then apply the active force towards connector in operating side, the change in location of A, B and C are similar to the above, no longer superfluous in detail herein
It states.
As interchangeable embodiment, locking buckle assembly can be applied on other pipe fittings to be fixed.
It can be seen from the above description that the above embodiments of the present invention realize following technique effect：
Fixing device is mainly used for being stuck in the fixation in abdominal cavity in sheath, establishes the dedicated stable channel of surgical instrument, Neng Goushi
Existing sheath is stuck in the good fixation at abdomen mini-incision, and installation is simple, and easy to operate, entrance that will not be too deep is internal, can be to prevent
Only sheath card deviates from abdominal cavity, and small to stomach wall mini-incision damaging surrounding tissue.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
