Description

A kind of dedicated hooking device of splanchnocoel Minimally Invasive Surgery percutaneous puncture

Technical field

The present invention relates to medical instruments fields, more particularly to a kind of dedicated hooking of splanchnocoel Minimally Invasive Surgery percutaneous puncture Device.

Background technique

Surgeon can usually block operating field sight when carrying out chest, laparoscopic surgery in a organized way, for the ease of behaviour Make, patient, which needs to suspend in midair to block with suture, is organized in stomach wall or the wall of the chest, keeps operating field apparent to improve precision of performing the operation, together When reduce Minimally Invasive Surgery notch.The seam that usual surgical operation person draws needed for being drawn by the pin hole of common puncture needle to outside body cavity Zygonema, or lead is punctured by body cavity from inside to outside with sewing needle, but since sewing needle is shorter, chest and abdomen wall is not easy to penetrate；Secondly Since suture is softer when lead reverse by common puncture hole, patient by pin hole drive in the wrong direction outside line sending when, need in body It is intracavitary to be clamped in line sending to puncture hole with Minimally Invasive Surgery, while vacuum extractor being recycled to aspirate lead outward by needle handle, it ties Fruit causes that normal pressure is difficult to maintain in patient's splanchnocoel and lead is time-consuming and laborious；Furthermore due to the limit of common needle length System, the patient more plump to chest and abdomen wall, puncture needle are also not easy to penetrate, and patient is to guarantee that surgical quality can select to increase minimally invasive hold Mouth replaces lead to suspend in midair with other instruments, and then increases the iatrogenic injury of patient.

Summary of the invention

In conclusion the purpose of the utility model is to provide a kind of dedicated hooking devices of splanchnocoel Minimally Invasive Surgery percutaneous puncture.

The purpose of this utility model is achieved through the following technical solutions:

A kind of dedicated hooking device of splanchnocoel Minimally Invasive Surgery percutaneous puncture, is transformed by puncture needle, puncture needle include needle handle and Needle point；The needle point of puncture needle is in spoon shape, and cross section profile is ellipse；Needle point spoon shape rim is equipped with opening；Opening width is 1.2mm, depth 1.4mm.

The distance of above-mentioned puncture needle needle handle to needle point is 160mm, internal diameter 1.6mm.

The utility model is transformed by carrying out certain research with anesthesia spinal needle to Medical anesthetic, can be convenient and efficient Suture is drawn out of splanchnocoel, draw suture from splanchnocoel to external when solving surgeon's chest and abdomen hysteroscope Minimally Invasive Surgery The practical operation of line is difficult.

Compared with the prior art, the utility model has the following advantages:

The gage system of operator can be changed in 1 the utility model, improves since suture is softer, passes through common puncture needle pin hole Driven in the wrong direction from inside to outside by body cavity lead when, operate time-consuming and laborious and low success rate of reality.

2, it when the utility model avoids operating to body cavity outer lead, is inhaled caused by suture by needle handle vacuum extractor Splanchnocoel in decompression, vacuum extractor can not had to completely.

3, the utility model, which is improved, cannot penetrate chest and abdomen wall since common needle length limitation bring patient punctures Operating difficulties.

4, the utility model reduces Minimally Invasive Surgery opening, shortens operating time, and source is cured caused by patient to reduce Property injury.

5, the utility model hooks suture and mentions line to outside body cavity, needle core resets excellent when surgical procedure proposes line step Point is: 1. sutures are not easy to slip 2. needle cores to be open by interior covering needle point, avoids hook company when mentioning line to chest abdominal wall tissue.

6, the alternative general pneumoperitoneum puncture needle of the utility model, substitution are completed the surgical application of pneumoperitoneum puncture needle, are accomplished One device is dual-purpose.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the structural schematic diagram of needle point in the utility model.

Specific embodiment

Illustrate to be described further the utility model with reference to the accompanying drawing:

As shown in Figure 1, 2, the dedicated hooking device of a kind of splanchnocoel Minimally Invasive Surgery percutaneous puncture, including puncture needle, described wears Pricker includes needle handle 1, needle point 2；The needle point 2 of puncture needle is in spoon shape, and cross section profile is ellipse；The 2 spoon shape rim of needle point Equipped with opening 3；3 width of opening is 1.2mm, depth 1.4mm.

Embodiment

By the surgery dedicated thread catcher of splanchnocoel Minimally Invasive Surgery percutaneous puncture (hereinafter referred to as thread catcher) band needle core, selecting In skin penetrating bring out into the open and lunge into thoracic cavity either abdominal cavity, paracentesis depth is intuitive visual under hysteroscope；Into after body cavity, by needle Core retracts to more than 2 inclined-plane of needle point, exposes thread catcher tip inlets 3, and the suture loop of required traction tissue is hung on hook At the opening 3 of line device, thread catcher needle core resets, and suture proposes body together with thread catcher at the opening 3 of needle point 2 together Outside chamber to skin, traction state needed for suture is adjusted, can conveniently complete the operation that hook line is drawn outside body cavity Step.

In addition, this thread catcher can be used as the pneumoperitoneum puncture needle of endoscope-assistant surgery, completes to puncture, surveys pressure and manufacture of intraocular gas Abdomen.
