Technical Field
The invention relates to the field of medical instruments, in particular to a single-hole laparoscope cannula.
Background
Compared with the traditional operation, the laparoscopic operation is popular with patients, especially has small scar after operation and meets the aesthetic requirements, young patients are more acceptable, and the minimally invasive operation is the general trend and pursuit target of surgical development. Currently, the golden standard of laparoscopic surgery is cholecystectomy, and most of the general surgical operations, laparoscopic surgery, are generally performed. Such as appendectomy, gastric and duodenal ulcer perforation repair, hernia repair, colectomy, splenectomy, adrenal gland resection, ovarian cyst removal, extrauterine pregnancy, hysterectomy and the like, almost all surgical operations can be adopted with the increasing perfection of laparoscopic techniques and the improvement of the operating level of laparoscopic surgeons.
Laparoscopes are instruments with miniature cameras. The laparoscopic surgery is a surgery performed by using a laparoscope and related instruments, a laparoscopic lens (the diameter is 3-10mm) is inserted into an abdominal cavity, an image shot by the laparoscopic lens is transmitted to a rear-stage signal processing system through an optical fiber by using a digital camera technology, and the image is displayed on a special monitor in real time. Then, the doctor analyzes and judges the state of the patient through images of different angles of the patient organ displayed on the monitor screen, and performs the operation by using a special laparoscope instrument.
During laparoscopic surgery, a laparoscope and surgical instruments are introduced into a human body through a laparoscopic cannula, and connection of various instruments outside the human body is realized. At present, the single-port laparoscope cannula used at home and abroad not only has a complex structure, but also has high price and inconvenient replacement, and needs professional operation of manufacturers. The laparoscope cannula belongs to a loss part, is very easy to damage due to improper use, cannot work once damaged, needs to be shut down for waiting for maintenance, and delays precious time for treatment of a patient.
How to provide a single-port laparoscope cannula which has simple structure, strong universality and easy replacement is a problem to be solved urgently at present.

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
FIG. 1 is a schematic view of the overall structure of a single port laparoscope cannula according to the present invention;
FIG. 2 is a schematic view of the front end opening of a single port laparoscopic cannula according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the single-port laparoscope cannula of the present invention is made of silicone, and includes a front opening 1, a rear opening 2 and an intermediate connecting part 3, wherein the rear opening 2 is a full-opening structure, and each instrument of the laparoscopic surgery extends into the cannula through the rear opening 2; front end opening 1 is semi-enclosed construction, including four big round holes 4 and a small circle hole 5, the silica gel material at above-mentioned five round hole borders all extends 1 ~ 2 centimetres with the back taper structure from the front end opening plane, each instrument of laparoscopic surgery operation in the human body stretches out the sleeve pipe outside through big round hole 4, because the border of big round hole is with back taper structure 6 and is extended 1 ~ 2 centimetres from the front end opening plane, therefore, the connecting rod of each instrument closely laminates with the silica gel material that extends, can prevent effectively that the internal body fluid of human body or blood from invading inside the sleeve pipe. The small round hole 5 is used for inserting into the pneumoperitoneum hole and injecting CO into the human body2In a similar way, the silica gel material extending out of the edge of the small round hole is tightly attached to the pneumoperitoneum hole catheter, so that body fluid or blood in a human body can be effectively prevented from invading the inside of the sleeve.
When the used instruments are less than four, the redundant large round hole can be closed, and the specific operation can be that the extended silica gel material is pulled back into the sleeve and is tied by a thread rope.
The large round hole, the small round hole and the corresponding extending parts are all made of silica gel and have strong elasticity, so the laparoscope instrument can be suitable for all the existing laparoscope instruments, and has strong universality. When the existing sleeve is damaged, each instrument can be conveniently sleeved by the sleeve.
In order to improve the controllability of the laparoscopic instrument on the external part of the human body, the opening at the rear end of the cannula is also provided with an outer ring 21 and a handle 22 at the outer edge thereof in the integral forming process, the outer ring 21 is used for limiting the position of the external part of the laparoscopic instrument, because the hole formed in the human body during the operation is as small as possible, the rear half parts of the instrument inserted into the human body are fastened together as much as possible, so that the tearing of the instrument on the hole of the human body during the operation is reduced. The handle is used for the doctor to adjust the position of the external part of the human body according to the position of the instrument in the human body, and therefore the flexibility of the working process of the instrument is improved.
Preferably, as shown in fig. 2, the closed part of the front opening of the sleeve is further provided with a cross-shaped reinforcing rib 6, four large circular holes 4 are symmetrically arranged in four divided areas of the reinforcing rib, a small circular hole 5 is arranged in one of the divided areas, a thickened part 7 is arranged at the center of the cross-shaped reinforcing rib 6, and the top of the thickened part is provided with an integrally-formed circular ring 8 (shown in fig. 1), wherein the circular ring is in a circular cake shape in the integrally-formed manufacturing process and is formed by punching. The ring 8 is connected to the outside of the opening at the rear end of the casing by a cord 9. When the laparoscopic instrument and the sleeve are required to be inserted into a human body, the cord 9 at the rear end of the sleeve is pulled, the closed part of the front end opening is tightened and tightly attached to the instrument, the instrument is inserted into the opening on the human body with the minimum diameter, then the cord 9 is loosened, the instrument is not fastened, and the laparoscopic instrument and the sleeve can be freely operated. When the instrument needs to be pulled out after the operation, the cord 9 at the rear end of the sleeve needs to be pulled, the front end of the sleeve is tightened, the human body is pulled out with the minimum diameter, and the diameter of the human body opening and the tearing of the opening are reduced as much as possible.
The single-hole laparoscope cannula has strong universality and can replace all the existing laparoscope instrument cannulas; moreover, the extension structure at the opening can ensure the close fit with the connecting rod of the laparoscopic instrument, and the body fluid or blood in the human body is effectively prevented from invading the inside of the sleeve.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
