Description
Technical field
The present invention relates to the field of medical instrument technology, specifically a kind of laparoscope with extension mechanism.
Background technique
Currently, laparoscopic surgery apparatus has been widely used for clinical abdomen, and in thoracic operation operation, laparoscope hand
Art has apparent advantage than traditional operation, has many advantages, such as that wound is small, it is fast to restore, pain is light, discharge is early.Through extensively by hand
Art doctor and many patients are received, but in clinical position, we can encounter some patients, according to state of an illness needs, it is necessary to hand
Art treats disease, and patient refuses the operation plan of the larger wound of tradition, in order to pursue beauty, is strongly required laparoscope invasive manner
Be operated, but patient again due to cardio-pulmonary function is poor, abdominal cavity or every flesh hernia, be difficult to be resistant to pneumoperitoneum pressure or discomfort
Close the patient of CO2 pneumoperitonium, traditional suspension method, although can accomplish to establish partial surgical space, due to devices call
The disadvantages of higher, abdomen leaves more suspention scratch, operative region exposure is insufficient.Increase operating difficulty to operator,
Increase operation risk simultaneously.
Summary of the invention
The purpose of the present invention is being directed to above-mentioned status, a kind of laparoscope with extension mechanism is provided.
A kind of the technical solution adopted by the present invention: laparoscope with extension mechanism, comprising: shank, the shank it is outer
Side is provided with extension mechanism, and the extension mechanism includes bearing, hinge eyes, extension support on front, flexible ring, body cradle, slip ring and stretches
Contracting part, the bearing are fixed on the outer surface of the shank, and the slip ring is set on the bearing, the hinge eyes and
The extensible member is fixed on the bearing, and described extension support on front one end and the slip ring are hinged, the other end and the flexible ring
Connection, described body cradle one end and the hinge eyes are hinged, and the other end and the extension support on front are hinged, the telescopic end of the extensible member
It is fixed with the slip ring.
Effect of the invention is: total light weight of the present invention, simple structure can rapidly strut tissue, convenient
The implementation of operation keeps surgical procedure easier, quick, practical.
Detailed description of the invention

Fig. 2 show the structural schematic diagram of extension mechanism in Fig. 1；
Fig. 3 show the structural schematic diagram of Fig. 2 middle (center) bearing；
The schematic perspective view of rubber pad in Fig. 1 shown in Fig. 4.
Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
Fig. 1, Fig. 2, Fig. 3 and Fig. 4 are please referred to, is a kind of signal of the laparoscope with extension mechanism provided by the invention
Figure.The laparoscope with extension mechanism includes: camera lens 5, shank 1 and handle 2, and the shank 1 is arranged in the camera lens 5
Front end, the shank 1 and the handle 2 connection, the outside of the shank 1 be provided with a rubber pad 3 and expand
Thermal change colour additive is distributed in the rubber pad 3 in mechanism 6, and the side of rubber pad 3 is provided with an arc groove 4, described
Arc groove 4 with and the outside of shank 1 be equipped with.
The extension mechanism 6 includes bearing 61, hinge eyes 62, extension support on front 63, flexible ring 64, body cradle 65, slip ring 66
And extensible member 67, the bearing 61 are fixed on the outer surface of the shank 1, the slip ring 66 is set in the bearing 61
On, the hinge eyes 62 and the extensible member 67 are fixed on the bearing 61, described 63 one end of extension support on front and the slip ring
66 is hinged, and the other end is connect with the flexible ring 64, and described 65 one end of body cradle and the hinge eyes 62 are hinged, the other end and institute
It is hinged to state extension support on front 63, the telescopic end of the extensible member 67 and the slip ring 66 are fixed.
The bearing 61 includes inner ring 611, ball 612 and outer ring 613, the outer surface of the inner ring 611 and the shank 1
Fixed, the fixed ring 62 and the extensible member 67 are fixed on the outer ring 613, and the slip ring 66 is set in the outer ring
On 613, the ball 612 is embedded between the inner ring 611 and the outer ring 613.
Further, the rubber pad 3 is cuboid.
Further, the arc groove 4 is semicolumn figure.
Further, the extensible member 67 is telescopic cylinder.
It is existing specifically, further including light source assembly and optical fiber component in the laparoscope with extension mechanism
Technology, details are not described herein.
Specifically, the rubber pad 3 has elasticity and toughness, friction be not easy it is scaling-off, can significantly deformation, rubber pad 3 sets
It is equipped with drop-center 4, groove 4 is the semicolumn bodily form, and diameter is rubbing with the common laparoscope shank diameter with extension mechanism
In can effectively increase rubber pad 3 with extension mechanism laparoscope shank 1 effective contact area.
Specific mode of operation are as follows: hold tight handle 2 for one when use, rubber pad groove 4 is close to shank by another hand
1, the grip that bending rubber pad 3 wraps shank 1, and applies 15kg or so, while moving repeatedly rubber pad 3 and reaching rubber pad 3
It is in sliding friction state with shank head 1.After about 20 seconds, shank 1 is since frictional heat generation, shank are whole warm repeatedly with rubber pad 3
Degree gradually rises, and when shank is integrally heated to 60 DEG C or so, rubber pad 3, which changes color tips heating, to be completed.Due to heat
Transfer principle, camera lens 5 are also heated, and 5 bulk temperature of camera lens is higher than environment temperature in abdominal cavity of patients at this time, and camera lens 5 is set at this time
Enter abdominal cavity not and will lead to vapor and agglomerated to the cold before camera lens, is achieved the effect that antifog；Protrude into abdominal cavity, it is sometimes desirable to expand tissue
When, extensible member 67 pushes the slip ring 66 close to the hinge eyes 62, and the extension support on front 63 and the body cradle 65 are along institute
The radial direction for stating shank 1 struts flexible ring 64, so that tissue be strutted, the shank 1 passes through axis with the extension mechanism 6
61 connections are held, the shank 1 still can be rotated relative to the extension mechanism 6, will not influence observation.
Total light weight of the present invention, simple structure, tissue can be strutted rapidly, facilitate the implementation of operation, make hand
The operation is more convenient for art, quick, practical.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
