[0031] Embodiment 1

[0032] This embodiment discloses a medical transparent visualization working sheath.

[0033] As Figures 1 to 6 shown, this embodiment includes a device main body 1. The device main body 1 includes a working sheath 2, a fixing member 3, and an expansion guide core 4. The fixing member 3 and the expansion guide core 4 are sleeved inside the working sheath 2. The fixing member 3 is arranged at the top of the working sheath 2. The expansion guide core 4 is screwed below the fixing member 3. An endoscope hole 5 and a drainage tube hole 6 are provided on the fixing member 3. A puncture drainage tube 7 is provided on the drainage tube hole 6. The puncture drainage tube 7 is sleeved with the expansion guide core 4.

[0034] The endoscope hole 5 is used to install an endoscope to achieve visual observation during the operation; the drainage tube hole 6 is used to connect the puncture drainage tube 7 for hematoma drainage operation. The dilation guide core 4 is provided with a through drainage tube placement hole 12, and the puncture drainage tube 7 is sleeved on the dilation guide core 4 through the drainage tube placement hole 12.

[0035] An endoscope fixator 8 is provided on the endoscope hole 5, and the endoscope hole 5 is screwed to the endoscope fixator 8.

[0036] The endoscope hole 5 is screwed to the endoscope fixator 8. This design enables the endoscope to be firmly fixed on the working sheath 2, and at the same time, the doctor can conveniently adjust the angle of the endoscope by rotating the endoscope fixator 8 to obtain the best surgical field of view and meet the observation requirements of different surgical scenarios.

[0037] A grip 9 is provided at the top of the working sheath 2.

[0038] The grip 9 facilitates the doctor's hand-held operation and improves the stability and accuracy of the operation.

[0039] A drainage tube inner core 10 is provided inside the puncture drainage tube 7.

[0040] During the puncture process, the drainage tube inner core 10 can enhance the hardness of the puncture drainage tube 7, facilitating accurate implantation into the intracranial hematoma cavity; after successful implantation, the drainage tube inner core 10 is removed, and then the drainage operation can be carried out.

[0041] Both the working sheath 2 and the dilation guide core 4 are made of transparent materials.

[0042] The transparent materials such as medical-grade transparent plastics or glass allow the doctor to observe the surrounding tissue conditions in real time and avoid accidental injuries.

[0043] Scale lines 11 are provided on the working sheath 2 and the dilation guide core 4.

[0044] The doctor can accurately control the insertion depth according to the scale lines 11 to ensure that the working sheath 2 accurately reaches the intracranial hematoma cavity and improve the accuracy of the operation.

[0045] At the beginning of the operation, first accurately implant the puncture drainage tube 7 with the drainage tube inner core 10 into the intracranial hematoma cavity, using the drainage tube inner core 10 to enhance the support of the puncture drainage tube 7 to ensure the accuracy of the puncture. After successful implantation, carefully remove the drainage tube inner core 10. At this time, a syringe can be used to perform a back-drawing operation through the puncture drainage tube 7 to initially drain the hematoma.

[0046] Next, sleeve the dilation guide core 4 on the puncture drainage tube 7, and then insert the dilation guide core 4 into the body. After that, withdraw the puncture drainage tube 7, and sleeve the main body of the working sheath 2 on the dilation guide core 4. Then, firmly fix the endoscope on the fixing member 3 through the endoscope fixator 8, and use the illumination function of the endoscope to determine the implantation position of the main body of the working sheath 2.

[0047] Finally, slowly insert the main body of the working sheath 2 along the dilating guide core 4 into the body until it reaches the intracranial hematoma cavity. Then, remove the dilating guide core 4 and properly fix the main body of the working sheath 2. During the whole operation, the transparent properties of the working sheath 2 and the dilating guide core 4 enable the doctor to observe the surrounding tissue conditions in real time and avoid damaging important structures; the scale lines 11 on the working sheath 2 and the dilating guide core 4 help the doctor accurately control the insertion depth, facilitating surgical operations and observing the hematoma drainage situation.

[0048] Usage method:

[0049] Preoperative preparation: Check whether all components of the working sheath 2 are intact and perform strict disinfection on the working sheath 2. Prepare auxiliary devices such as endoscopes and syringes required for the operation.

[0050] Implantation of the puncture drainage tube 7: Under the guidance of imaging equipment, accurately implant the puncture drainage tube 7 with the drainage tube inner core 10 into the intracranial hematoma cavity, and pay attention to avoiding damaging the surrounding tissues during the operation.

[0051] Drainage and dilation operations: After successful implantation, carefully remove the drainage tube inner core 10, and use a syringe to perform a back-drawing operation through the puncture drainage tube 7 to initially drain the hematoma. Then, sleeve the dilating guide core 4 on the puncture drainage tube 7, and then insert the dilating guide core 4 into the body.

[0052] Insertion of the working sheath 2: Withdraw the puncture drainage tube 7, and sleeve the main body of the working sheath 2 on the dilating guide core 4. Firmly fix the endoscope on the fixing member 3 through the endoscope holder 8, turn on the endoscope lighting function, and determine the implantation position of the main body of the working sheath 2. Slowly insert the main body of the working sheath 2 along the dilating guide core 4 into the body until it reaches the intracranial hematoma cavity. Then, remove the dilating guide core 4 and properly fix the main body of the working sheath 2.

[0053] Surgical operation and observation: During the operation, the doctor observes the hematoma condition and the surrounding tissues through the endoscope, and uses the transparent properties and scale lines 11 of the working sheath 2 and the dilating guide core 4 to monitor the surgical operation in real time. After the operation, carefully remove the working sheath 2 and the endoscope, and clean, disinfect, and maintain the used instruments for future use.
