Description

Technical Field

[0001] The invention relates to the medical industry, and in particular to a tissue and organ suspension device. Background Art

[0002] During minimally invasive surgery, the surgical field of view is often affected by some tissues and organs. In order to obtain a better surgical field of view during surgery, many surgical instruments for retraction and fixation have been developed, such as three-leaf fan forceps (Chinese patent document CN201120103023, Chinese patent document CN101933822A). However, the instrument needs to be applied through a minimally invasive channel, and an additional assistant is required to operate and fix the instrument.

[0003] Chinese patent document CN204542251U provides a "single-port laparoscopic tissue suspension fixator", which consists of a spring part and hook parts on both sides. The spring is located in the middle, and its length can be selected according to the patient's body shape and surgical requirements. The two hook parts are respectively an acute-angle needle body and a semi-arc needle body, which are connected by the middle spring part. In single-port laparoscopic surgery, the tissue fixator is inserted into the abdominal cavity through the umbilical puncture cannula, and the acute-angle needle body is clamped by the needle holder, passing through the tissue to be fixed, and then the semi-arc needle body at the other end penetrates the peritoneum and fixes it to the abdominal wall, thereby fixing the tissue to the surface of the abdominal wall, which is convenient for exposing the surgical field. Chinese patent document CN205251595U provides a "disposable tissue suspension device", which does not occupy the minimally invasive channel and does not require additional assistants to operate. The effect of retracting and fixing tissues and organs to expose the surgical field is also relatively good. However, both the single-port laparoscopic tissue suspension fixator and the disposable tissue suspension fixator require puncture of tissues and organs during use, which will cause certain damage to the tissues and organs, and some tissues and organs cannot be punctured. Another method is to puncture the abdominal wall for tissue suspension fixation after suturing the tissue with a fine needle through the abdomen, but this method is cumbersome to operate, and the silk thread has a certain cutting effect on the tissues and organs. Long-term silk thread pulling is easy to damage the tissues and organs, and may cause related complications.

[0004] Chinese patent document CN205672086U provides a "Laparoscopic Liver Suspension Sheet", which includes a suspension surface, a pair of threading tubes, multiple anti-slip points and a pair of anti-cutting incisions. After establishing pneumoperitoneum, two puncture needles with double-headed medical silk threads are inserted respectively under the laparoscope directly viewing the xiphoid process. The ends of the silk threads are fixed near the xiphoid process outside the body with hemostatic forceps. The two puncture needles are pulled out of the body through the 10mm main operation hole of the laparoscope at one time using laparoscopic instruments. The needle and thread are separated and cut, and the four silk threads pulled out of the body are successively inserted into the threading tube from the sharp-angle anti-cutting interface of the sterilized laparoscopic liver suspension with a straight needle, and then passed out from its obtuse anti-cutting interface. The two silk threads passing through the same interface are tied into a knot, and a total of two knots are tied. The silk thread head fixed near the xiphoid process is pulled so that the laparoscopic liver suspension sheet is pulled again through the same laparoscope main operation hole into the abdominal cavity, and fixed near the gastric cardia with a biological clamp. Continue to pull the extracorporeal silk thread to the appropriate strength to achieve good non-destructive exposure of the surgical area. Although this instrument can avoid damaging tissues and organs, the operation is relatively cumbersome and will take up more surgical time. Summary of the invention

[0027] See also Figures 1 to 5 A tissue organ suspension device 100 includes a suspension belt 10 and an introduction structure 20.

[0028] In the first embodiment, the suspension belt 10 includes a suspension bar 12. The suspension bar 12 is provided with a plurality of connection holes 120. The plurality of connection holes 120 are evenly spaced and arranged on the suspension bar 12. The suspension bar 12 is made of a polymer material such as medical rubber or silica gel and the suspension bar 12 can be folded.

[0029] In the second embodiment, the suspension belt 10 includes two suspension bars 12 and a suspension net 14. The two suspension bars 12 are fixed to the two ends of the suspension net 14 respectively. Each suspension bar 12 is provided with a connecting hole 120. The two suspension bars 12 and the suspension net 14 have the same width. The suspension bars 12 are made of polymer materials such as medical rubber or silica gel and the suspension bars 12 can be folded. The suspension net 14 is made of polymer materials or textile materials. The suspension net 14 can be made into various specifications according to the size of the organ.

[0030] In the second embodiment, the structure of the suspension belt 10 is substantially the same as that of the second embodiment, except that the width of the suspension net 14 is greater than the width of the two suspension bars 12. The end of the suspension net 14 close to the suspension bars 12 is a bevel so that the width of the end of the suspension net 14 is the same as the width of the suspension bars 12.

[0031] The introduction structure 20 includes a housing 21 and a push rod 22. The housing 21 includes an introduction portion 210 and a grip portion 212. The grip portion 212 is located at one end of the introduction portion 210 and is fixed to the introduction portion 210. The introduction portion 210 is hollow to form a cavity 214. The push rod 22 includes a rod body 220 and a handle 222. The handle 222 is fixed to the rod body 220. The diameter of the handle 222 is greater than the diameter of the rod body 220. The length of the rod body 220 is greater than the length of the cavity 214.

[0032] When using the tissue and organ suspension device 100, first load the suspender 30 into the introduction needle. Fold the sling 10 and put it into the cavity of the introduction structure 20. The introduction structure 20 passes through the abdominal wall 200 through the puncture device and enters the abdominal cavity. Push the push rod 22 to guide out the folded sling 10, fix one end of the sling 10 with a grasping forceps, and withdraw from the introduction structure 20. Then use the grasping forceps to grab the other end of the sling 10 from the bottom of the tissue and organ 201 that needs to be retracted, so that the two ends of the sling 10 are parallel, and the introduction needle punctures the two connecting holes 120 that overlap at the two ends of the sling 10, and then pushes the main body of the sling 30 and unfolds it to form a "T" shape. At this time, the introduction needle can be withdrawn from the abdominal cavity, and the sling 30 can be pulled from the outside of the abdominal wall 200 to adjust the target tissue and organ 201 to a satisfactory position. The position of the sling 30 can be locked in vitro with a locking device, and the surgical operation can be performed. It does not occupy the minimally invasive channel, and can effectively retract and fix the tissue and organ 201 to better expose the surgical field of view, while not causing damage to the tissue and organ 201. The final result is shown in Figure 5 .

[0033] When the operation is finished or the sling 30 needs to be removed, the tail end strip of the sling 30 body is cut off first, the sling 30 body is pulled out of the abdominal cavity, and then the tail end strip and the sling belt 10 are taken out from the minimally invasive channel with clamps.

[0034] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
