Problems solved by technology

In the case of an incision, such non-parallel or diverging opposing walls may degrade subsequent healing of the bone because of suboptimal contact between the reassembled surfaces
[0012] In addition, since in known laser devices the distance to the tissue is usually kept rather short, the laser device may impede or prevent direct visualization of the intervention area
This can lead to frequent movement of the laser unit by the surgeon to enable direct visual inspection of the ablation process
Furthermore, such a short distance leaves no room for other instruments such as retractors or suction tubes for soft tissue, and limits the space available for laser device positioning or fitment in the robot's last stage The operability of the laser device

Embodiment Construction

[0067] In the following description, certain terms may be used for convenience and are not intended to limit the present invention. The terms "right", "left", "up", "down", "under" and "above" refer to directions in the drawings. Terminology includes the explicitly mentioned term, its derivatives and terms with similar meanings. In addition, spatially relative terms such as "beneath", "below", "lower", "above", "upper", "proximal ", "distal", etc., can be used to describe the relationship of one element or feature to another element or feature as shown in the figure. These spatially relative terms are intended to encompass different positions and orientations of the device in use or operation in addition to the position and orientation shown in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" or "above" the other elements or features. Thus, the exemplar...

Abstract

A tissue ablation laser device (100), comprising: a laser source (110) configured to generate a base laser beam (140); and a beam shaping optic (120) configured to receive the base laser beam (140) and to convert the base laser beam (140) into a transmit laser beam (143). The beam shaping optics (120) is further configured to focus the base laser beam (140) such that the emitted laser beam (143) has a focus angle (142) of about 10 DEG or less.

Description

technical field [0001] The invention relates to a tissue ablation laser device according to the preamble of independent claim 1, and more particularly to a method of ablation of tissue eg by means of such a tissue ablation laser device. [0002] A tissue ablation laser device of the type having a laser source configured to generate a base laser beam and beam shaping optics configured to receive the base laser beam and convert the base laser beam into an emitted laser beam may be used to ablate tissue for cutting, milling ( mill) or drill tissue. The tissue may in particular be human or animal hard tissue. Background technique [0003] For cutting and drilling various types of materials in many technical fields, it is becoming more and more popular to use devices that apply a laser beam to ablatively remove material, rather than using mechanical tools. In fact, laser-based cutting, milling or drilling is common today in industrial applications, as it allows efficient and fl...
